A cleaning unit includes a cleaning member eliminating a waste toner from an image carrier, a waste toner conveying body conveying the waste toner in a conveying channel to a waste toner case, a shutter having an ejecting port and a shutter moving mechanism moving the shutter between an opening position and a closing position. Via the ejecting port, the conveying channel and waste toner case are communicated. The shutter contacts with/separates from a seal preventing a leak of the waste toner from the ejecting port. When the shutter is rotated in one direction and moved to the opening position to make an outer end face of the shutter contact with the seal, the ejecting port is opened. When the shutter is rotated in another direction and moved to the closing position to make the outer end face of the shutter separate from the seal, the ejecting port is closed. |
