PURPOSE:To improve the sticking strength between a photosensitive layer and a base and prevent the formation of interference fringes in an image by making the base surface where a photoconductive layer is formed rugged in a nearly regular groove shape at specific height and at specific peak-to-peak pitch. CONSTITUTION:The surface of the base 1 is roughened and the photoconductive layer 3 is formed thereupon directly or across an intermediate layer 2 to constitute a photosensitive body, and said roughened surface is so made rugged that the height of each projection is about 0.3-2mum and the peak-to-peak distance 1a-1a' is <=20mum. This roughened surface is obtained by, for example, the skimming and finishing of lathe work and surface finishing by a grindstone. The photoconductive layer 3 is formed on the surface of the base 1 directly or across the intermediate layer 2 to improve the sticking strength of the photosensitive layer and also obtain good picture quality without any interference fringe. Further, not only a cylindrical base, but also a flat plate and a flexible base are used to obtain excellent good quality similarly. |
