Abstract
A fusing system, method of fusing with a fuser member having a thermally stable FKM hydrofluoroelastomer surface for fusing thermoplastic resin toners to a substrate in an electrostatographic printing apparatus has a polyorgano T-type amino functional oil release agent, the oil having predominantly monoamino functionality per active molecule to interact with the hydrofluoroelastomer surface to provide a substantially uniform interfacial barrier layer to the toner and a low surface energy film to release the toner from the surface.
Claims7
A fluid release agent for application to a fuser member having a thermally stable hydrofluoroelastomer surface for fusing thermoplastic resin toners to a substrate in an electrostatographic printing apparatus comprising amino functional oil having the formula:
- ##STR4## where 50.ltoreq.n.ltoreq.200, p is 1 to 5, 50.ltoreq.m .ltoreq.200 and q is 1 to 200 wherein at least 85% of the polyorgano aminosiloxane functional chains have p equal to 1 said oil having predominantly monoamino functionality per active molecule to interact with said hydrofluoroelastomer surface to provide a substantially uniform interfacial barrier layer to said toner and a low surface energy film to release said toner from said surface.
