Image drum and method of manufacturing the same

摘要

An image drum, for selectively adsorbing a toner on the image drum so as to form an image in a printing apparatus, includes a hollow cylindrical drum body and an electrode member. The electrode member includes a flexible substrate adapted to surround an outer circumferential surface of the drum body; a plurality of ring-shaped electrodes formed circumferentially on a top surface of the flexible substrate so as to be electrically insulated from one another; and a control unit disposed on a bottom surface of the flexible substrate for independently applying a voltage to each of the ring-shaped electrodes. The electrode member is disposed on the outer circumferential surface of the drum body.
