ABSTRACT:
A release agent donor member for a toner fixing system wherein a polymeric release agent having functional groups is applied to the surface of a fuser member has a base member, an intermediate conformable silicone elastomer layer and an elastomer release agent donor layer comprising poly(vinylidenefluoride-hexafluoropropylenetetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent, a metal oxide present in an amount sufficient to interact with the polymeric release agent having functional groups to transport a sufficient amount of the polymeric release agent to provide an interfacial barrier layer between the fusing surface and the toner and being substantially unreactive with said elastomer, the elastomer release agent donor layer having been cured from a solvent solution thereof with a nucleophilic curing agent and in the presence of 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.
