Image drum and a manufacturing method thereof

Abstract

An image drum and method of producing the same is provided. The drum includes a drum body having a pair of semi-cylindrical members, each being oppositely bonded and having a bonding surface having electrodes being separated from one another by insulating areas, and line electrodes formed on the periphery; a control unit including conductive parts corresponding to the line electrodes, and nonconductive parts interposed between the conductive parts, and disposed inside the drum body; and a connecting member electrically coupling the line electrodes to the control unit. The method includes cutting a cylindrical member into two semi-cylindrical members; oxidizing the surfaces of the members; forming electrodes on each of the cut surfaces; partially oxidizing a substrate; bonding the two semi-cylindrical members across the substrate such that the electrodes and the conductive parts couple together; and forming line electrodes on the periphery of the members.
