Abstract
PURPOSE:To enhance abrasion resistance by applying and baking a mixed solution of a PTFE resin and a PFA resin to the member to be coated. CONSTITUTION:The offset preventive layer 1 of the outermost layer of a fixing roller is formed by coating it with the mixed solution of the polytetrafluoroethylene (PTFE) and the copolymer (PFA) of tetrafluoroethylene and perfluoroalkyl vinyl ether, and baking the roller. Since the PFA resin 5 is rich in fluidity, the PTFE resin particles 4 are contained in a dotted state in the PFA resin 5, thus permitting occurrence of pinholes in the formed coat to be prevented, adhesion of the particles of both resins in a heat-softened state to be enhanced, the hardness of the resin 4 to reinforce the softening of the resin 5, and consequently, the offset preventive layer 1 to be hardly scratched by a cleaning pad, a separating edge, copying papers, and the like.
