ABSTRACT:
A cylindrical tubular substrate for an electrophotographic photoconductor is made of a conductive resin. The substrate is smoothly rotatable about its axis of rotation, securely grounded, and easily and inexpensively manufactured. It has a cylindrical tube portion and a flange portion with a gear and a shaft through-hole. These portions can be integrated as a unit of a material containing an electrically conductive resin as the main component. Alternatively, the shaft is integrated unitarily with the substrate by single-step molding. Or further, a flange, made of a resin with high sliding wear resistance and with a gear and a shaft through-hole, or a previously molded flange made of a resin with high sliding wear resistance and with a gear and a shaft insert-molded to the flange, with an electric conductor, is disposed in an assembling molding step at an end of a cylindrical tube made essentially of a conductive resin.
