Abstract
A process for fusing toner to paper. This process employs a release fluid containing an aminofunctional polyorganosiloxane, and a fuser member having a fluoro-elastomer fusing surface layer that contains Fe2O3 filler.
Claims32
A process for fusing toner residing on a substrate to the substrate, the process comprising:
- (a) applying a release agent comprising an aminofunctional polyorganosiloxane to the fusing surface layer of a fuser member to provide a release agent-treated fusing surface layer, the fuser member comprising:
- (1) a fuser base;
- (2) the fusing surface layer, comprising:
- (A) at least one fluoroelastomer, and
- (B) Fe2O3 filler particles;
- and
- (b) contacting the toner with the release agent-treated fusing surface layer.
4 more elements
A fuser member, for a toner fusing system or process, comprising:
- (a) a base;
- and
- (b) a fusing surface layer comprising:
- (i) at least one fluoroelastomer;
- and
- (ii) Fe2O3 filler particles, wherein the Fe2O3 comprises Fe2O3 prepared from at least one sulfur-containing iron compound.
