  • Publication number: 20150241814
    Abstract: Waste toner scraped off a surface of a photoreceptor drum is transported by a toner conveyor screw of a cleaner and sent into a process pipe. The process pipe includes an end that does not have a screw, and a moth-eye structure is provided on an inner wall surface of the end by applying a moth-eye sheet. Thus, the waste toner is prevented from remaining at the end of the process pipe.
