PURPOSE:To prevent triboelectrification by forming on an elastic layer >=2 resin layers of the surface layer contg. no filler and the internal layer contg. a filler both by coating and heat treatment methods. CONSTITUTION:An elastic rotating body is composed of a core metal, the elastic layer made of rubber, preferably, silicon rubber, surrounding the core, and at least one resin layer formed by coating it with a tetrafluoroethylene or perfluoroethylene resin contg. a filler and heat treaing the resin, and the surface layer made of said resin contg. no filler, likewise formed on this layer, thus permitting the lower resin layer to be lowered in resistance and difficult to be electrified, and enhanced in durability by the high adhesion between the elastic layer and the resin layer. |
