  • Waste toner collecting container and process unit
    Patent number: 9223288
    Abstract: Disclosed is a waste toner collecting container used in an image forming device for collecting waste toner and a process unit having the waste toner collecting container. An assembly of a development unit and the photoreceptor unit is fixedly connected to the waste toner collecting container. The development unit is configured to supply toner to a photoreceptor in the photoreceptor unit.
