Abstract

PURPOSE:To provide a seamless belt excellent in adhesive properties with an electrically conductive layer, while high dimensional accuracy, flatness and long life are kept by arranging an elastic resin layer inside of the cylindrical film composed of biaxially oriented thermoplastic polyester resin. CONSTITUTION:Pressurized air is introduced into a tubular film obtained by extruding polyethylene terephthalate by an extruder, and a biaxially oriented tubular film is obtained by drawing. Polyester elastomer is similarly extruded by the extruder and is drawn, thereby to obtain a tubular film. The tubular film is cut and is caused to cover a metallic drum 7 as an elastic resin layer 7. Next, the biaxially oriented polyester tubular film is cut and the obtained cylindrical film 6 is caused to cover the metallic drum 7 through the elastic resin layer 8. After two cylindrical films have adhered to each other by heat treatment, they are pulled out from the metallic drum. The cylindrical film is dipped into the conductive adhesive solution containing carbon black, where by carbon film is formed on the inner surface of the cylindrical film.
