A charging control device render off a DC voltage applied to the charging member after transfer of the toner image and while the intermediary transfer member is carrying the toner image. A charging member cleaning control devices permits, when a signal for starting image formation is inputted, a cleaning operation for discharging toner deposited on the charging member to the image bearing member before starting the image formation.
