ABSTRACT:
A method of using multilayered member for fusing thermoplastic resin toner images to a substrate in a fuser system of the type wherein a polymeric release agent having functional groups is applied to the surface of the fuser member. The multilayered fuser member has in sequential order a base support member, an adhesive layer comprising a copolymer of vinylidene fluoride and hexafluoropropylene and at least 20% by weight of the adhesive layer of a coupling agent comprising at least one organo functional silane and an activator, a tie coat layer of active ingredients comprising a copolymer of vinylidene fluoride and hexafluoropropylene and an outer elastomeric fusing surface comprising a copolymer of vinylidene fluoride and hexafluoropropylene and containing a metal oxide present in an amount sufficient to interact with a polymeric release agent having functional groups to provide an interfacial barrier layer between said fusing surface and toner.
