Abstract

PURPOSE: To prevent electrostatic latent image potential change owing to long time leaving, and to prevent the occurrence of any image unevenness in continuous copying with simple constitution by moving a photoreceptor and performing light irradiation while the copier is ready for copying.
CONSTITUTION: A drum 1 is rotatively driven clockwise and is formed with electrostatic latent images by a primary charger 2, a charging and exposing device 3, an entire surface exposing device 4. The latent images undergo transfer 7 after developing 5. While the apparatus is in a copying standby state, light irradiation is performed by an entire surface exposing light source 4 and a front exposing light source 9 while the drum 1 is rotated at a 30mm/s peripheral speed. The rotating speed of the drum 1 is made the speed at the latent image or slower than this.
