Abstract
An electrophotographic apparatus utilizes a photoconductor which avoids a concentration of electric field due to the voltage applied from the charging member to the irregular spot on the outer surface of the cylindrical conductive substrate, and as a result, electrical breakdown of the photosensitive layer is suppressed and lowering of the charged voltage is prevented, so that a critical printing fault, such as a black spot on the printed material, does not occur. The photoconductor includes a cylindrical conductive substrate and an organic photosensitive layer on the outer surface of the substrate, and is used in an electrophotographic system including a contact charging process, wherein the outer surface of the substrate is finished to a mirror surface by means of surface cutting.
