METHOD OF FORMING THIN RESISTIVE HEATING LAYER, HEATING MEMBER INCLUDING THE THIN RESISTIVE HEATING LAYER, AND FUSING UNIT INCLUDING THE HEATING MEMBER

摘要

A method of forming a thin film resistive heating layer, the method including: forming a polymer layer by extruding a polymer paste, in which an electrically conductive filler is dispersed, by using an extrusion molding operation, on an outer circumferential surface of a cylindrical member; and forming a thin film resistive heating layer by making an outer diameter of the polymer layer uniform by using a ring blading operation.
