ABSTRACT:
A fuser member for fusing thermoplastic resin toner images to a substrate has an aluminum base member and an elastomer fusing surface of a poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent, the elastomer having been cured from a solvent solution thereof with a nucleophilic curing agent soluble in the solution and in the presence of 5 or less than 4 parts by weight of inorganic base per 100 parts of polymer, the inorganic base being effective to at least partially dehydrofluorinate the vinylidenefluoride, and an adhesive layer between the surface of said aluminum base member and the elastomer fusing surface, the adhesive layer having been cured from a solvent solution of a poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent and from about 6 to 20 parts by weight per 100 parts by weight of said poly(vinylidenefluoride hexafluoropropylene-tetrafluoroethylene) of an amino silane represented by the formula: ##STR1## where R can be an alkyl group having 1 to 7 carbon atoms; R' can be an alkyl group having 1 to 7 carbon atoms or a polyalkoxyalkyl group of less than 7 carbon atoms; Y is an amino group or an amino substituted alkyl, or a polyamino substituted alkyl, or an alkenylalkoxy amino, or an aryl amino group of less than 15 carbon atoms, h is 1 to 3, b is 0 to 2, q is 1 or 2 and h+b=3.
