The method of fusing thermoplastic resin toner images to a substrate in a fuser including a heated thermally stable FKM hydrofluoroelastomer fusing surface at elevated temperature prepared in the absence of anchoring sites for a release agent of heavy metals, heavy metal oxides, or other heavy metal compounds forming a film of a fluid release agent on the elastomer surface of an amino functional oil having the formula: ##STR1## where 50.ltoreq.n.ltoreq.200, p is 1 to 5, and R.sub.1, R.sub.2 and R.sub.3 are alkyl or arylalkyl radicals having 1 to 18 carbon atoms, R.sub.4 is an alkyl or arylalkyl radicals having 1 to 18 carbon atoms and a polyorganosiloxane chain having 1 to 100 diorganosiloxy repeat units, and R.sub.5 is hydrogen, alkyl or arylalkyl radicals having 1 to 18 carbon atoms, the oil having sufficient amino functionality per active molecule to interact with the hydrofluoroelastomer surface in the absence of a heavy metal and heavy metal anchoring sites to provide an interfacial barrier layer to the toner and a low surface energy film to release the toner from the surface; contacting the toner image on the substrate with the filmed heated elastomer surface to fuse the toner iage to the substrate and permitting the toner to cool.
The method of fusing thermoplastic resin toner images to a substrate comprising providing a heated thermally stable hydrofluoroelastomer fusing surface at elevated temperature, said hydrofluoroelastomer fusing surface having been prepared in the absence of anchoring sites for a functional release agent of heavy metals, heavy metal oxides, or other heavy metal compounds, forming a film of a fluid release agent on said elastomer surface comprising a fluid amino functional oil having the formula:
A heated pressure fusing system for fusing thermoplastic toner in an electrostatographic printing apparatus in which a heated fuser member and a backup pressure member define a fusing arc to fuse toner images to a substrate, said fuser member comprising a thermally stable hydrofluoroelastomer fusing surface said FKM hydrofluoroelastomer fusing surface having been prepared in the absence of anchoring sites for a release agent of heavy metals, heavy metal oxides, or other heavy metal compounds, means to deliver a release agent to said surface, said release agent comprising a fluid amino functional oil having the formula:
