Abstract

PURPOSE:To obtain a certain level of surface potential of a photoreceptor regardless of the mode, by switching the bias voltage applied to the photoreceptor between the normal mode and the automatic original feed mode. CONSTITUTION:In the case of the consecutive copying in the normal mode, a latent image 1a is formed intermittently on the surface of a photoreceptor 1. An undesired image erasing light source 7 is irradiated to the undesired image region between latent images 1a and 1b. In the case of the automatic original feed mode, the automatic original exchanging time A is required. Meanwhile the light source 7 is continuously turned on to erase an undesired latent image 1c in the section A. However, the optical fatigue is caused on the surface of the photoreceptor 1 by the lighting of the source 7. As a result, the surface potential of the photoreceptor 1 increases and decreases as shown by the broken lines to the potential (solid lines) of the normal mode.
