Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A cleaning method for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising the steps of: supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed; laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying substrate; cooling said heat-soluble material to solidify said heat-soluble material; and separating said image-carrying substrate and said cleaning sheet member from each other such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
Claim 2
Dependent Claim
116 words
A cleaning method for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising the steps of: supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed; laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying substrate; cooling said heat-soluble material to solidify said heat-soluble material; and separating said image-carrying substrate and said cleaning sheet member from each other such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
Claim 3
Dependent Claim
19 words
A cleaning method according to claim 1, wherein said heat-soluble material is the same material as said image-forming material.
Claim 4
Dependent Claim
118 words
A cleaning apparatus for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising: means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying substrate; and means for separating said image-carrying substrate and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
Claim 5
Dependent Claim
118 words
A cleaning apparatus for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising: means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying substrate; and means for separating said image-carrying substrate and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
Claim 6
Dependent Claim
19 words
A cleaning apparatus according to claim 3, wherein said heat-soluble material is the same material as said image-forming material.
Claim 7
Dependent Claim
145 words
A printing apparatus comprising: erasing means for erasing an image-forming material formed on a surface of an image-carrying sheet to obtain an erased image-carrying sheet; and means for forming a new image-forming material on said surface of said erased image-carrying sheet according to an image data, wherein said erasing means comprises: means for supplying a heat-soluble material in heated and melted condition onto said surface of said image-carrying sheet on which said image-forming material has been formed; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying sheet; and means for separating said image carrying sheet and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying sheet to said cleaning sheet member together with the solidified heat-soluble material.
Claim 8
Dependent Claim
145 words
A printing apparatus comprising: erasing means for erasing an image-forming material formed on a surface of an image-carrying sheet to obtain an erased image-carrying sheet; and means for forming a new image-forming material on said surface of said erased image-carrying sheet according to an image data, wherein said erasing means comprises: means for supplying a heat-soluble material in heated and melted condition onto said surface of said image-carrying sheet on which said image-forming material has been formed; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying sheet; and means for separating said image carrying sheet and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying sheet to said cleaning sheet member together with the solidified heat-soluble material.
Claim 9
Dependent Claim
20 words
A printing apparatus according to claim 5, wherein said cleaning sheet member is in the form of an endless belt.
Claim 10
Dependent Claim
149 words
A printing apparatus comprising: means for forming an image-forming material on a surface of an image-carrying member according to an image data; means for transferring said image-forming material formed on said surface of said image-carrying member to a member to be printed; and cleaning means for removing said image-forming material remained untransferred on said surface of said image-carrying member, said cleaning means comprising: means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying member; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying member; and means for separating said image-carrying member and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying member to said cleaning sheet member together with the solidified heat-soluble material.
Claim 11
Dependent Claim
149 words
A printing apparatus comprising: means for forming an image-forming material on a surface of an image-carrying member according to an image data; means for transferring said image-forming material formed on said surface of said image-carrying member to a member to be printed; and cleaning means for removing said image-forming material remained untransferred on said surface of said image-carrying member, said cleaning means comprising: means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying member; means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying member; and means for separating said image-carrying member and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying member to said cleaning sheet member together with the solidified heat-soluble material.
