An electrophotographic photoconductor is formed of a metallic base drum and a photoconductive layer formed thereon. The base drum is an electroseamed tube prepared by high-frequency welding of a tubular metallic plate or strip. The electroseamed tube may be subjected to extruding or drawing, straightness improving by use of correcting rollers, or machining, grinding, abrasion finish, electro-polishing or anodizing for treatment of its surface.
