<P>PROBLEM TO BE SOLVED: To provide a cylindrical core body capable of easily extracting a resin film formed on a surface of the core body, a method for regenerating it and a manufacturing method of an endless belt made by using the cylindrical core body, in manufacturing the endless belt using a cylindrical core body provided with a heat-resistant resin layer formed on the surface of a metallic substrate. <P>SOLUTION: The cylindrical core body provides the heat-resistant resin layer with a releasing agent layer and is made by forming a heat-resistant resin-coated film by applying a heat-resistant resin solution to the surface of the metallic substrate, by applying a mold releasing agent to the surface of the coated film at a state where the coated film is not dried and/or unreacted to form a mold releasing coated film and then giving a heating and drying treatment to it. <P>COPYRIGHT: (C)2007,JPO&INPIT |
