Abstract

PURPOSE:To obtain a device having a short temperature rising time by composing a heat roller of a cylindrical core part whose surface is insulated, a ceramic layer formed on the surface of the core part, and an insulating coating formed on its surface. CONSTITUTION:Around external surface of cylindrical core part 27 made of a metallic pipe, ceramic insulating layer 28, for example, is formed by melt-spraying, etc. On the surface of this ceramic insulating layer 28, ceramic powder layer 29 of high resistance is formed by melt-spraying, etc., and this ceramic powder layer 29 constitutes a heating source layer together with feeding rings 30a and 30b fitted at both its ends in contact. In this constitution, after ceramic powder layer 29 is heated, it will not take a long time to obtain the temperature required for fixation at the heat roller external circumferential surface, and conseqently the temperature rising time can be shortened.
