Fuser member

A 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 comprising a base member and an elastomer fusing surface comprising poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent, a metal oxide present in said fusing surface 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 and being substantially unreactive with said elastomer, said elastomer having been cured from a solvent solution thereof with a nucleophilic curing agent soluble in said solution and in the presence of less than 4 parts by weight of inorganic base per 100 parts of polymer, said inorganic base being effective to at least partially dehydrofluorinate the vinylidenefluoride.
