Abstract:
1. An image forming apparatus comprising: an image bearing member configured to be rotatable and to bear a latent image; a developing apparatus configured to develop the latent image into a toner image by using a toner containing an external additive; a transfer apparatus configured to transfer the toner image to a member to be transferred; a cleaning apparatus configured to perform cleaning of the toner from the image bearing member after transfer; and a control apparatus configured to electrically charge the image bearing member to a predetermined polarity during an image-formation period, and electrically charge the image bearing member to a polarity opposite the predetermined polarity during a non-image-formation period, and to execute a cleaning mode in which the image bearing member is rotated one rotation or more in a non-contact state with the developing apparatus so that a surface of the image bearing member charged to the opposite polarity, may pass the cleaning apparatus to remove the external additive on the surface of the image bearing member.
