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.
