摘要：PURPOSE: To eliminate an electrically-charged memory of a photoreceptor before forming an image. CONSTITUTION: A cleaning roller 12 is slid on a surface of an OPC photoreceptor 1 in contact with the surface to remove an object adhered on the surface of the photoreceptor 1. Negative charges are collected on the cleaning roller 12 due to friction and electrical charging at this time. When the photoreceptor 1 is left in contact with negative charges, a positive electrically- charged memory is generated on its surface. The photoreceptor 1 is rotated and driven in the arrow direction R1 and an alternating current voltage is applied to an electrically-charged memory removal device 15 by a controller 51 immediately before the photoreceptor 1 arrives at the electrically-charged memory removal device 15 to form an alternating electric field between the photoreceptor 1 and it. The electrically-charged memory M is removed by passing the memory M through the alternating electric field.
