Abstract
An image forming apparatus includes a drum for bearing a toner image; a rotatable belt onto which the toner image is to be transferred from the drum; a primary transfer member for primary transferring the toner image from the drum onto the belt; a secondary transfer member for secondary transferring the toner image from the belt onto a transfer material; and a charging member for electrically charging toner remaining on the belt. The image forming apparatus is capable of executing a belt cleaning mode in which the toner remaining on the belt is electrically charged, and a charging member cleaning mode in which the toner is transferred from the charging member onto the belt and then onto the drum. When the charging member cleaning mode is executed, the charging member is moved at least once from a belt separation position or away from a belt contact position.
