Abstract

PURPOSE: To increase the sensitivity of the photoreceptor, by repeating the charging of the same polarity as that when forming an image and the exposure in prior to formation of the image by means of a drum containing a photoreceptor coated with the insulated layer on the surface.
CONSTITUTION: The transparent insulating protective layer 1c is coated on the photoconductive material layer 1b, thus forming the drum 1. With this drum 1, the charging is carried out by the transfer charger 8, and then the previous history sencitization of the 1st stage by the erasing charger 12. After this, the sencitization of the 2nd stage is carried out by the sencitizing unit 13 consisting of the subcharger 4 and the suberaser 15 and through the charging-to-exposure process. In such way, the charging function of the charger 8 is used also to the charging process of the previous history sencitization.
