A low load fuser member for heating and fusing high quality toner images onto an image carrying substrate is provided. The low load fuser member includes a soft, low durometer and thermally non-conductive first elastomeric material member for forming a relatively large fusing nip at a relatively low load; a second and thermally conductive elastomeric material forming an intermediate layer over the first elastomeric material member; and a toner image release layer formed over the intermediate layer for facilitating release of fused toner images.

Disclosed is a fuser member comprising a substrate, a layer thereover comprising a polymer or an elastomer, and, on the layer, a coating including mercapto- and amino-functionalities comprising from about 0. 05 mole percent to about 1. 00 mole percent mercapto groups and from about 0. 0001 mole percent to about 0. 06 mole percent amino groups, wherein the ratio of mercapto to amino mole percent values is at least 2. The layer preferably is a fluoropolymer or fluoroelastomer filled with a metal oxide (CuO, AlO, etc. ).

A method of making a low surface energy material such as a fuser member comprising providing a shaped fluoroelastomer, preparing a solvent solution of a polyorganosiloxane having reactive functionality and the formula: ##STR1## where R is an alkyl, alkenyl or aryl group having less than 19 carbon atoms or an aryl group substituted with an alkyl or alkenyl group having less than 19 carbon atoms, the functional group A is epoxy, vinyl, acrylic, allylic or methacrylic and n is 2 to 350, contacting the fluoroelastomer with the solution to form at least a thin coating of the polyorganosiloxane on said fluoroelastomer and exposing the coated fluoroelastomer to a level of radiation to form a thin surface layer of the polyorganosiloxane grafted to said fluoroelastomer.

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.
