Abstract
A release agent donor member for a toner fixing system, the donor member includes: a base member; an optional intermediate layer; and an outermost layer of a polymeric composition containing a cured interpenetrating network or (a) fluorocarbon elastomer and (b) at least one silicone elastomer of polyfunctional poly(C.sub.(1-6) alkyl) siloxane polymer; polyfunctional poly(C.sub.(1-6) alkyl)arylsiloxane polymer; and combinations thereof; wherein a functionalist release agent is applied to the outer surface of the outermost layer; and wherein the outermost layer contains a metal oxide in an amount sufficient to interact with the functionalist release agent. The fluorocarbon elastomer can be a terpolymer of vinylideneflouride, hexafluoropropylene, and tetraflouroethylene, wherein the vinylideneflouride is present in an amount greater than 45 mole percent.
