ABSTRACT:
An image forming apparatus includes an executing portion, which executes a first removing sequence and a second removing sequence when removing a toner image borne on an intermediate transfer member. The first removing sequence passes the toner image through a primary transfer portion, which is applied with a voltage having a same polarity as the predetermined polarity, and thereafter removing the toner image by the removing portion which forms a cleaning electric field. The second removing sequence removes the toner image by the removing portion, which forms the cleaning electric field, without passing the toner image through the primary transfer portion. A selecting portion means selects between the first removing sequence and the second removing sequence in accordance with a toner amount per unit area of the toner image borne on the intermediate transfer member at a stoppage of the intermediate transfer member.
