ABSTRACT:
A cleaning device for an electrophotographic apparatus for removing toner particles which remain on a photoconductive element after image transfer. A cleaning blade is movable into contact with the photoconductive element for removing toner particles. A scraping member is held in contact with the cleaning blade by a predetermined pressure to scrape the toner particles off the cleaning blade. When the cleaning blade is moved toward the photoconductive element, an urging member or a resilient member urges the scraping member away from the cleaning blade. The cleaning blade is, therefore, prevented from exerting a load on the scraping member while the cleaning blade cleans the photoconductive element.
