Abstract (en)
[origin: EP0657789A2] The method of fusing thermoplastic resin toner images (14) to a substrate (12) in a fuser including a heated thermally stable FKM hydrofluoroelastomer fusing surface (2) 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 (2) of an amino functional oil having the formula: <CHEM> where 50</=n</=200, p is 1 to 5, and R1, R2 and R3 are alkyl or arylalkyl radicals having 1 to 18 carbon atoms, R4 is an alkyl or arylalkyl radicals having 1 to 18 carbon atoms and a polyorganosiloxane chain having 1 to 100 diorganosiloxy repeat units, and R5 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. <IMAGE>
