Abstract: A fuser belt comprising an amorphous fluoropolymer outer layer for fusing a thermoplastic resin toner image to a substrate produces high gloss images, wherein the amorphous fluoropolymer has the structure: ##STR1## in which m is 20 mole percent or 35 mole percent and n is 65 mole percent or 80 mole percent.

Abstract: A fuser member is provided comprising a support; a fluoroelastomer layer on said support comprising a fluoroelastomer consisting essentially of from 42 to 58 mole percent vinylidene fluoride, 26 to 44 mole percent tetrafluoroethylene, and 5 to 22 mole percent hexafluoropropylene.

Abstract: A fuser for fixing particulate imaging material to a receiver sheet, includes two rollers which engage each other at a fixing nip, wherein pressure is used in fixing the particulate imaging material to the receiver sheet; and at least one of the fusing rollers having a surface formed from zirconia ceramic or its composites which has a hardness greater than 12 GPa and toughness greater than 6 MPa.sqroot.mm.

Abstract: This invention provides a release agent consisting of a blend of non-poly(alkylene oxide)-functionalized poly(organosiloxane) fluid and poly(alkylene oxide)-functionalized poly(organosiloxane) fluid and an antioxidant which when used at elevated temperatures does not separate into two phases and does not cause an objectionable odor, or pump failure. The release agent is particularly suited for application to a fuser member for fusing toner images to a receiver.

Abstract: A release oil barrier layer is coated over the silicone rubber cushion layer of a toner fusing roll by means of a coating composition having a low VOC content and comprising an aqueous dispersion of a fluorocarbon polymer in particulate form and a water-dispersible polyurethane.

Abstract: A fuser member for fusing a thermoplastic resin toner image to a substrate having:(a) a rigid metal core;(b) a base cushion layer covering the metal core wherein the base cushion comprises a condensation cured polydimethylsiloxane or an addition cured silicone rubber;(c) a cured fluoroelastomer layer covering the base cushion layer;(d) an aminosilane adhesive coveting the fluoroelastomer layer; and(e) an amorphous fluoropolymer covering the aminosilane adhesive layer.

Abstract: A method of making a fuser member such as a fuser roller, pressure roller, or fuser belt, comprising of bonding an outermost fluoropolymer resin layer to an inner fluoroelastomer layer by means of a fluoropolymer-containing polyamide-imide primer layer.

Abstract: A process for controlling gloss to fused toner images, comprising the steps of:A. passing an element bearing an unfused toner image through a fusing zone, a cooling zone and a release zone; andB. bringing the element bearing the unfused toner image into pressure contact with a fusing belt, thereby fusing the toner image to the element; characterized in that the fusing belt is a metal having(i) an unmatted powder coated tetrafluoroethylene/hexafluoropropylene (FEP) copolymer to provide a fused toner image having a coating gloss of 54-64;(ii) an unmatted powder coated polytetrafluoroethylene-co-perfluoropropyl vinylether copolymer (PFA) to provide a fused toner image having a coating gloss of 11-18 and(iii) an unmatted aqueous spray coated blend of polytetrafluoroethylene (PTFE) and polytetrafluoroethylene-perfluorinated vinyl ether (PFA) to provide a fused toner image having a coating gloss of 5-12.

Abstract: A fuser for fixing electrostatographic images comprising a fusing roll and a pressure roll is disclosed. The pressure roll has a rigid metal core coated with an amorphous fluoropolymer. The fluoropolymer has a surface energy up to 16 dyne/cm and a coefficient of friction from 0.4 to 1.0.

Abstract: This invention provides a release agent consisting of a blend of poly(organosiloxane) fluid and phenol-functionalized poly(organosiloxane) fluid which when used at elevated temperatures does not produce insoluable or undesirable by-products or gellation. The release agent is particularly suited for application to a fuser member for fusing toner images to a receiver.

Abstract: Coated fuser members such as a fuser roller, pressure roller, or fuser belt, and the method of making the coated fuser members are disclosed. The release coating comprises an outermost layer of fluoropolymer resin uniquely bonded to a fluoroelastomer layer by means of a fluoropolymer-containing polyamide-imide primer layer.

Abstract: Toner fusing rolls having an oil barrier layer composed of a substrate coated with a fluorocarbon-silicone polymeric composition which is obtained by concurrently curing a fluorocarbon copolymer, a nucleophilic fluorocarbon-curing agent and a heat-curable polyfunctional poly(C.sub.1-6 alkyl)phenylsiloxane polymer.
