Abstract

An image-forming apparatus includes a control unit configured to perform a first collection operation in which toner that has passed a position at which the charging unit and the intermediate transfer member are in contact with each other is moved from the intermediate transfer member to the image bearing member. The control unit is also configured to perform a second collection operation in which toner having been moved from the charging unit to the intermediate transfer member is moved from the intermediate transfer member to the image bearing member. The control unit controls rotation speed of the image bearing member in such a manner that the rotation speed of the image bearing member in the second collection operation is slower than the rotation speed of the image bearing member in the first collection operation.
