Fixing roller and its manufacturing method

Abstract

Abstract PURPOSE:To improve an image quality by preventing offset, and to make a cleaning of the fixing roller easy by polishing the surface of a mother material, after coating a fluorine resin on the surface of the mother material and baking, and subsequently baking it at the temp. of more than a m.p. of the fluorine resin. CONSTITUTION:The fluorine resin is spray-coated on the core metal 3 of the fixing roller 1 in such that the layer having 15mu thickness is formed, and subsequently, the obtd. coatings is baked at 380 deg.C, followed by cooling it. And, the coating and baking of said resin are repeated and then, the surface of the mother material is effected a buffing to form a surface roughness of 2mu, followed by baking it at the temp. of 360-380 deg.C. The flat surface layer 2 is formed by removing a foreign material with the buffing, and lessening the roughness of the surface of the fixing roller, followed by melting said surface with baking. Thus, the toner does not intrude, and the offset is prevented, thereby improving the fixing ability and making the cleaning of the fixing roller easy by a cleaning means 13.
