<p>An image forming apparatus includes a movable image bearing member, a charger for electrically charging the image bearing member, latent image forming device for forming a latent image with use of the charger, a developing device for developing the latent image formed by the latent image forming device with toner electrically charged to a polarity the same as a polarity to which the image bearing member is charged by the charger, image transfer member contactable to a back side of a transfer material to transfer a toner image provided by the developing device from the image bearing member to the transfer material, a voltage application device for applying a voltage to the transfer member, the voltage application device applying a voltage having a polarity the same as that of the toner to the transfer member during non-transferring operation, and a device for providing different potentials for a portion of the image bearing member to be opposed to the image transfer device during the non-transfer action by said image transfer member and for a portion of said image bearing member to be opposed to said image transfer member during transfer action by the image transfer member.</p> |
