Abstract
In a copying apparatus having a photosensitive member such as a drum, good reproductivity and image density results from applying a proper charging potential to the photosensitive substance on the drum. The optimum charging potential for each drum can be predetermined and a code or indicia representative of such optimum potential may be attached or otherwise appended to the drum. This code is read by a suitable sensor which in turn controls the charging potential applied to the drum.
