  • Waste toner transport unit and image forming apparatus
    Patent number: 10268155
    Abstract: A waste toner transport unit includes a waste toner transport path through which waste toner removed from a circumferential surface of an image carrier is transported, a transport member that transports the waste toner along the waste toner transport path, and a movement restrictor that restricts the movement of the waste toner in a process of waste toner transportation. The waste toner transport path includes an area in which an inner bottom surface is inclined and the area constitutes the movement restrictor. The transport member is disposed such that a rotation shaft extends along the inclined inner bottom surface.
