A method of making a fuser roller comprising: providing a fuser roller an outer layer comprising a fluorothermoplastic polymer; and annealing the outer surface of the outer layer through contact the outer layer by means of heat and pressure.

Method of making fuser member

A method for producing a replaceable fuser member including a thin, seamless or welded high temperature nickel sleeve, a base cushion positioned around the sleeve and an outside topcoat applied over the base cushion elastomer layer. The sleeve is replaceable on a machine mandrel positioned in an electrophotographic copying machine in a fuser section of the electrophotographic copying machine. The method includes the use of a mandrel having a coefficient of thermal expansion similar to that of the sleeve to support the sleeve during positioning of a cured base cushion layer around the sleeve and a cured topcoat layer over the cured base material.

The present invention is an apparatus for refurbishing a fusing member. The apparatus includes a fusing member that contacts the toner image on a receiver medium and fuses the toner image to the receiver medium. The fusing member has an outer contact surface of a fluorothermoplastic resin The apparatus includes a tooling member positionable adjacent to the outer contact surface of the fusing member such that a pressure nip is formed between the outer contact surface of the fusing member and the tooling member. A heat source is provided for transferring heat to the fusing member and the tooling member, wherein the surface of the fuser member is engagable with the tooling member to rotate at a speed of at least 1 rpm at a pressure of at least 5 psi and at a temperature of at least 10&#xb0; C. below the thermoplastic melting temperature of the outer contact surface for a time sufficient to resurface of the outer surface of the fuser member.

Electrophotographic apparatus

The fuser members of this invention include a core member that includes a rigid outer surface. An adhesion promoter layer comprising silane or epoxy silane coupling is disposed on the outer surface of the core member. A resilient layer comprising an elastomer is disposed on the adhesion promoter layer. A tie layer is disposed on the resilient layer, the tie layer being made of fluoropolymers, fluoroelastomers, fluorocarbon thermoplastic copolymers and mixtures thereof. A primer layer, disposed on the tie layer, comprising perfluoroalkoxy resin and trifluoroethylene-perfluoroethyl vinyl ether-perfluoroethylene vinyl phosphate or a mixture of perfluoroalkoxy resin and trifluoroethylene-perfluoroethylvinyl ether; and an outer layer of fluoropolymer resin made from polytetrafluoroethylene, polyperfluoroalkoxy-tetrafluoroethylene, polyfluorinated ethylene-propylene and blends thereof is disposed on the primer layer.

Fuser member

The present invention is a fuser member that includes a core member having a rigid outer surface. A resilient layer made of an elastomer is disposed on outer surface. A primer layer of perfluoroalkoxy resin and trifluoroethylene-perfluoroethylvinyl ether-perfluoroethylene vinyl phosphate or a mixture of perfluoroalkoxy resin and trifluoroethylene-perfluoroethylvinyl bonds the resilient layer and an outer layer. The outer layer comprises fluoropolymer resin selected from the group consisting of polytetrafluoroethylene, polyperfluoroalkoxy-tetrafluoroethylene, polyfluorinated ethylene-propylene, and blends thereof.

The fuser members of this invention include a core member that includes a rigid outer surface. A resilient layer comprising an elastomer is optionally disposed on the cylindrical outer surface of the core member. A tie layer is disposed on the resilient layer or the outer surface if no resilient layer is present, the tie layer being made of fluoropolymers, fluoroelastomers, fluorocarbon thermoplastic copolymers and mixtures thereof. An outer layer of fluoropolymer resin made from polytetrafluoroethylene, polyperfluoroalkoxy-tetrafluoroethylene, polyfluorinated ethylene-propylene and blends thereof, is disposed on the tie layer.
