Abstract
A multilayered fuser 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 fuser member has a base support member, a thermally conductive silicone elastomer layer, an amino silane primer layer, an adhesive layer and an elastomer fusing surface comprising poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) a metal oxide present in the fusing surface to interact with the polymeric release agent to provide an interfacial barrier layer between the fusing surface and the toner and substantially unreactive with the elastomer, the elastomer having been cured from a solvent solution with a nucleophilic curing agent soluble in the solution and in the presence of 4 parts by weight of inorganic base per 100 parts of polymer, the adhesive layer having been cured from a solvent solution of the above composition from which the fusing surface is cured and from about 5 to about 10% by weight of a coupling agent represented by the formula: ##STR1## where R can be an alkyl having 1 to 4 carbon atoms; R' can be an alkyl group having 1 to …
