Abstract
Abstract Disclosed herein is a multilayer fuser member (10) which includes a first layer (14) of an elastomeric material; an oil-impervious second layer (16), preferably a fluoroelastomer; and (3) a bonding layer (15) intermediate the first and second layers in which the proportion of the elastomeric material to the oil-impervious material gradually varies from substantially only the elastomeric material to substantially only the oil-impervious material. A method of making the fuser member by a spraying technique is also disclosed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
A multilayer member (10; 30) for fusing toner images to a receiver comprising a first layer (14; 34) of an elastomeric material, a second layer (16; 36) of a material which is resistant to absorption of fuser oil, and a bonding layer (15; 35) intermediate said first and second layers for bonding said first and second layers, characterized in that said bonding layer (15; 35) comprises a blend of said elastomeric and oil-resistant materials in which the proportion of the elastomeric material to the oil-resistant material gradually varies, in a direction from the first layer (14; 34) toward the second layer (16; 36), from substantially only the elastomeric material to substantially only the oil-resistant material.
Claim 2
Dependent Claim
115 words
A multilayer member (10; 30) for fusing toner images to a receiver comprising a first layer (14; 34) of an elastomeric material, a second layer (16; 36) of a material which is resistant to absorption of fuser oil, and a bonding layer (15; 35) intermediate said first and second layers for bonding said first and second layers, characterized in that said bonding layer (15; 35) comprises a blend of said elastomeric and oil-resistant materials in which the proportion of the elastomeric material to the oil-resistant material gradually varies, in a direction from the first layer (14; 34) toward the second layer (16; 36), from substantially only the elastomeric material to substantially only the oil-resistant material.
Claim 3
Dependent Claim
16 words
The member as defined by Claim 1, characterized in that said oil-resistant material comprises an elastomer.
Claim 4
Dependent Claim
25 words
The member as defined by Claims 1 or 2, characterized in that said first and second layers (14; 34; 16; 36) comprise high temperature-resistant elastomers.
Claim 5
Dependent Claim
27 words
The member as defined by Claims 1 to 3, characterized in that said oil-resistant material comprises a crosslinked fluoropolymer having repeating units of tetrafluoroethylene and perfluoroalkyl perfluorovinylether.
Claim 6
Dependent Claim
26 words
The member as defined by Claims 1 to 3, characterized in that said elastomeric material comprises a silicone material and said oil-resistant material comprises a fluoropolymer.
Claim 7
Dependent Claim
37 words
The member as defined by Claim 5, characterized in that said elastomeric material comprises a silicone elastomer and said oil-resistant material comprises a fluoroelastomer selected from the group consisting of fluorosilicone elastomer and vinylidene fluoride-based fluoropolymeric elastomers.
Claim 8
Dependent Claim
30 words
The member as defined by Claim 1, characterized in that the thickness of said first layer (14; 34) is substantially greater than the thickness of said second layer (16; 36).
Claim 9
Independent Claim
100 words
A method for forming a resilient, oil-impervious member for fusing toner images to a receiver, characterized by the steps of: spraying a base member (12; 32; 70) with a first material comprising an elastomer; while spraying such base member with said first material, spraying such base member with a second material which is substantially impervious to oil; gradually increasing the relative proportion of said second material to said first material until only said second material is sprayed; and continuing to spray said second material only to form an oil-impervious layer (16; 36) of said second material atop said first material.
Claim 10
Independent Claim
100 words
A method for forming a resilient, oil-impervious member for fusing toner images to a receiver, characterized by the steps of: spraying a base member (12; 32; 70) with a first material comprising an elastomer; while spraying such base member with said first material, spraying such base member with a second material which is substantially impervious to oil; gradually increasing the relative proportion of said second material to said first material until only said second material is sprayed; and continuing to spray said second material only to form an oil-impervious layer (16; 36) of said second material atop said first material.
Claim 11
Dependent Claim
14 words
The method of Claim 8, characterized in that said second material comprises an elastomer.
Claim 12
Dependent Claim
24 words
The method of Claim 8 or 9, characterized in that said first material comprises a silicone material and said second material comprises a fluoropolymer.
Claim 13
Dependent Claim
35 words
The method of Claim 8, characterized in that said first material comprises a silicone elastomer and said second material comprises a fluoroelastomer selected from the group consisting of fluorosilicone elastomers and vinylidene fluoride-based fluoropolymeric elastomers.
Claim 14
Dependent Claim
24 words
The method of Claim 8, characterized in that said second material comprises a crosslinked elastomeric fluoropolymer having repeating units of tetrafluoroethylene and perfluoroalkyl perfluorovinylether.
