Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
98 words
A fuser member comprised of a substrate, thereover a layer of a silicone rubber including an inorganic particulate filler therein, wherein said inorganic filler selected from the group consisting of a metal, metal alloy, metal compound and silicon oxide, and a renewable release film over the layer of the silicone rubber comprised of silicone hydride oil formed by reacting said silicone hydride oil with the filler particles exposed on the surface of the silicone rubber layer, wherein the film is renewable upon wear of the film by reaction of additional silicone hydride oil with the exposed filler particles.
Claim 2
Dependent Claim
98 words
A fuser member comprised of a substrate, thereover a layer of a silicone rubber including an inorganic particulate filler therein, wherein said inorganic filler selected from the group consisting of a metal, metal alloy, metal compound and silicon oxide, and a renewable release film over the layer of the silicone rubber comprised of silicone hydride oil formed by reacting said silicone hydride oil with the filler particles exposed on the surface of the silicone rubber layer, wherein the film is renewable upon wear of the film by reaction of additional silicone hydride oil with the exposed filler particles.
Claim 3
Dependent Claim
103 words
A fuser member comprised of a substrate, thereover an adhesive layer, a layer of a silicone rubber including an inorganic particulate filler therein over the adhesive layer, wherein said inorganic filler selected from the group consisting of a metal, metal alloy, metal compound and silicone oxide, and a renewable release film over the silicone rubber layer comprised of silicone hydride oil formed by reacting said silicone hydride oil with the filler particles exposed on the surface of the silicone rubber layer, wherein the film is renewable upon wear of the film by reaction of additional silicone hydride oil with the exposed filler particles.
Claim 4
Dependent Claim
103 words
A fuser member comprised of a substrate, thereover an adhesive layer, a layer of a silicone rubber including an inorganic particulate filler therein over the adhesive layer, wherein said inorganic filler selected from the group consisting of a metal, metal alloy, metal compound and silicone oxide, and a renewable release film over the silicone rubber layer comprised of silicone hydride oil formed by reacting said silicone hydride oil with the filler particles exposed on the surface of the silicone rubber layer, wherein the film is renewable upon wear of the film by reaction of additional silicone hydride oil with the exposed filler particles.
