Abstract
PURPOSE: To avoid accumulation of generated heat and increase the durability, by covering the heating element disposed on the surface of metal roll through an electric insulating layer with a heat conductive insulating elastic body.
CONSTITUTION: A metal roll 1 is treated with primer or the like as required, and is wrapped with an elastic sheet excelling in thermal conductivity and electric resistance which is gaged by a specified thickness, thereby forming an electric insulating layer 2. A heating element 3, i.e., a surface heating element having a heating element circuit made of metal foil formed on the surface of elastic body of good thermal conductivity by etching method is wound around the layer 2 so that the heating element circuit may be situated outside, or linear heating elements are directly wound around the layer 2 at specified intervals. Then, an uncured elastic body 4 excelling in thermal conductivity and electric resistance being gaged to the specified thickness to form a surface layer is uniformly wound around the heating element 3, and is charged in a forming die to harden the elastic body, then a heating fixing roll is accomplished after heating treatment.
