An image forming apparatus includes an image bearing member for carrying a toner image, a movable intermediary transfer member for receiving the toner image from the image bearing member, a primary transfer member for primary transfer of the toner image from the image bearing member onto the intermediary transfer member, a secondary transfer member for being supplied with a voltage and for secondary transfer of the toner image from the intermediary transfer member onto a transfer material, and a first toner charging member. A first charging member rubs a surface of the intermediary transfer member with movement thereof, and a second charging member moves in contact with the intermediary transfer member, thereby transferring toner remaining on the intermediary transfer member after the secondary transfer back to the image bearing member from the intermediary transfer member simultaneously with the primary transfer at the primary transfer station. |
