Abstract
An image forming apparatus includes a movable photosensitive member; a toner image forming device for forming a toner image on the photosensitive member; a transfer device for electrostatically transferring the toner image from the photosensitive member to a transfer material at a transfer position; and a transfer material carrying member for carrying the transfer material to feed the transfer material to the transfer position. The transfer device transfers the image while the transfer material is on the transfer material carrying member, and after the image is transferred, the transfer material having the toner image transferred thereon and carried on the transfer material carrying member is contacted to the photosensitive member. There is also provided a charger for charging the photosensitive member, wherein at least a part of the photosensitive member making the contact is charged by the charger in a period between its passage through the transfer position and the contact, so as to be given an electric potential at which the toner image forming device does not deposit the toner to the photosensitive member.
