Abstract
Method for manufacturing an image-forming element having a hollow cylindrical drum body with a metallic outer layer and provided on its outer circumferential surface with a plurality of circumferentially extending electrodes which are electrically insulated from one another and from the drum body. The steps include cutting grooves into the metallic outer layer of the drum body, forming an insulating surface layer at least on the internal walls of the grooves by converting the surface of the metallic outer layer into an insulating substance, and filling the grooves with electrically conductive material.
