Abstract
An image forming apparatus includes an image bearing member; an intermediary transfer member; a controller; and a cleaning unit. The cleaning unit includes a cleaning member for collecting a residual toner in contact with the intermediary transfer member, a charging member, which is provided downstream of the cleaning member with respect to a movement direction of the intermediary transfer member, for electrically charging the residual toner, and an accommodating member for accommodating the residual toner. The controller is capable of executing an operation in a discharging mode in which the toner is discharged from the charging member onto the intermediary transfer member. When the operation in the discharging mode is executed, the cleaning unit collects the toner, discharged from the charging member on the intermediary transfer member, by the cleaning member and then accommodates the collected toner in the accommodating member.
