Patent ID: 7056578

Claim:
A fuser member for a toner fusing system, comprising: (a) a fuser base; and (b) a fusing surface layer comprising; (i) a fluoroelastomer; (ii) nonfibrillatable and autoadhesive plastic particles, comprising at least about 25 percent by volume of the fusing surface layer; and (iii) a discontinuous phase dispersed through the fluoroelastomer continuous phase in the form of domains, said discontinuous phase comprising a polymer comprising an elastomer selected from the group consisting of perfluoropolyethers silicones and fluoroelastomers; wherein said nonfibrillatable and autoadhesive plastic particles comprises a fluororesin selected from the group consisting of polytetrafluoroethylenes, fluorinated ethylene propylenes, copolymers of tetrafluoroethylene and ethylene and copolymers of tetrafluoroethylene and perfluoroalkyl vinyl ether, wherein said nonfibrillatable and autoadhesive plastic particles comprise a mean particle diameter of from about 0.1 microns to about 20 microns, wherein said fluororesin has a molecular weight of from about 25,000 to about 250,000.
