Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
A fusing device for use in a xerographic reproducing apparatus for fixing a resin-based powder image to a substrate comprising a fusing member having a water-degradable silicone rubber outer surface; means for heating the outer surface of the fuser member to form thereon a degradation product in the presence of water; means for applying water to the surface of the fuser member; and means for contacting the heated fuser member with a substrate having a resin-based powder thereon.
Claim 2
Dependent Claim
78 words
A fusing device for use in a xerographic reproducing apparatus for fixing a resin-based powder image to a substrate comprising a fusing member having a water-degradable silicone rubber outer surface; means for heating the outer surface of the fuser member to form thereon a degradation product in the presence of water; means for applying water to the surface of the fuser member; and means for contacting the heated fuser member with a substrate having a resin-based powder thereon.
Claim 3
Dependent Claim
36 words
The fusing device of claim 1 wherein the means for applying water to the water-degradable surface of the fuser member is a wick applicator in contact with the fuser member surface and a source of water.
Claim 4
Dependent Claim
32 words
The fusing device of claim 1 wherein the means for applying water to the water-degradable surface of the fuser member is at least one water spraying device proximate the fuser member surface.
Claim 5
Dependent Claim
35 words
The fusing device of claim 1 wherein the means for applying water to the water-degradable surface of the fuser member is a humidity chamber proximate at least part of the surface of the fuser member.
Claim 6
Dependent Claim
34 words
The fusing device of claim 1 wherein the means for applying water to the water-degradable surface of the fuser member is a pad in contact with the fuser member and a source of water.
Claim 7
Dependent Claim
34 words
The fusing device of claim 1 wherein the means for applying water to the water-degradable surface of the fuser member is a brush in contact with the fuser member and a source of water.
