Abstract

PURPOSE:To eliminate a thin film formed by a low surface energy material caused on the surface of a photoreceptor and to prevent the disturbance of a picture such as white lines, etc., by performing properly a copying action in a state under which no transfer paper is supplied in the mode except an ordinary copying action. CONSTITUTION:A copying action is properly carried out before and after an ordinary copying action and in the state of no transfer paper is supplied. As a result, the filming phenomenon is considerably suppressed. In this case, it is wise to avoid the waste of the toner. For this purpose, the surface potential of a photoreceptor is set at a low level during a developing action. For one method, the application of voltage to a charging corona charger 2 is cut off. For another method, the entire surface of the photoreceptor is exposed (to fully open an erase lamp 3, etc.) after the electric charging caused by said charger 2. The surface potential of the photoreceptor that goes into a development part is set lower than the bias potential of development.
