Abstract
Abstract A transfer sheet drying device for an electrophotographic copying machine which comprises a heating plate 2 having a plurality of narrow grooves 5 cut in a parallel direction with the copy sheet direction of movement, said heating plate 2 being provided as a transfer sheet transporting device disposed prior to a transferring station. A copy sheet keep member 6 rotatably provided on said heating plate 2 cooperates therewith to form an area through which the transfer sheet passes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
Reproduction apparatus comprising: a photosensitive drum; means for forming a latent image on said drum; means for rendering said image visible with a transferable powder; sheet means to which said visible image is transferred; means for conveying said sheet means from a sheet means supply into contact with said drum whereby said image is transferred to said sheet means; means for conditioning said sheet means one at a time prior to their contact with said drum to thereby enhance image transfer thereto; said means for conditioning said sheet means being disposed between said sheet means supply and said drum and comprising means for differentially drying said sheets in a direction perpendicular to the direction of movement thereof and extending across the width of said sheet means, said means for differentially drying said sheet means comprising a heating plate and a roller between which said sheets move, said plate being provided with a plurality of grooves extending in the direction of movement of said sheet means.
Claim 2
Dependent Claim
165 words
Reproduction apparatus comprising: a photosensitive drum; means for forming a latent image on said drum; means for rendering said image visible with a transferable powder; sheet means to which said visible image is transferred; means for conveying said sheet means from a sheet means supply into contact with said drum whereby said image is transferred to said sheet means; means for conditioning said sheet means one at a time prior to their contact with said drum to thereby enhance image transfer thereto; said means for conditioning said sheet means being disposed between said sheet means supply and said drum and comprising means for differentially drying said sheets in a direction perpendicular to the direction of movement thereof and extending across the width of said sheet means, said means for differentially drying said sheet means comprising a heating plate and a roller between which said sheets move, said plate being provided with a plurality of grooves extending in the direction of movement of said sheet means.
Claim 3
Dependent Claim
19 words
Apparatus according to claim 1 including a pre-heater preceding said roller in the direction of movement of said sheets.
Claim 4
Dependent Claim
166 words
Reproduction apparatus comprising: a photosensitive drum; means for forming a latent image on said drum; means for rendering said image visible with a transferable powder; sheet means to which said visible image is transferred; means for conveying said sheet means from a sheet means supply into contact with said drum whereby said image is transferred to said sheet means; means for conditioning said sheet means one at a time prior to their contact with said drum to thereby enhance image transfer thereto; said means for conditioning said sheet means being disposed between said sheet means supply and said drum and comprising means for differentially drying said sheets in a direction perpendicular to the direction of movement thereof and extending across the width of said sheet means, said means for differentially drying said sheet means comprising a belt and a heating plate between which said means move said heating plate being provided with a plurality of grooves extending in the direction of movement of said sheet means.
Claim 5
Dependent Claim
