Abstract
After a transferring process, a first predetermined voltage is applied to a transfer unit to charge a photosensitive drum surface to a first predetermined constant voltage. At the same time, a memory removing member is grounded. Therefore, a voltage difference is produced between the transfer unit and the memory removing member. This voltage difference causes the toner remaining on the memory removing member to be transferred to the photosensitive drum. In other words, the toner remaining on the memory removing member is redeveloped on the photosensitive drum whereby the cleaning of the memory removing member is conducted. Here, the memory removing member is a device for removing the toner from the photosensitive drum.
