摘要： A cleaning unit includes a cleaning member, an ejection member, a delivering member, and a flicker. The cleaning member contacts an object to be cleaned moving in a given direction, and removes waste material from the object to be cleaned. The ejection member, disposed in an area distanced from the object to be cleaned, transports the waste material removed from the object to be cleaned to outside of the cleaning unit. The delivering member delivers the waste material to a transport-effective area of the ejection member. The delivering member includes a vane rotating device including a rotation axis and a vane attached on the rotation axis. The vane rotating device rotates to deliver the waste material to the ejection member. The flicker contacts a free end of the vane to cause a flicker movement to the vane at a position over the transport-effective area of the ejection member.
