Abstract
A cleaning device includes: a collection member configured to contact a photosensitive member, on which an electrostatic latent image is configured to be formed, and collect foreign substances on the photosensitive member; a shaft configured to attract the foreign substances from the collection member so as to make the foreign substances cling thereto; a scraping member configured to contact the shaft and scrape the foreign substances cling on the shaft; and a housing configured to accommodate the collection member and the shaft, wherein the scraping member is mounted to the housing. The scraping member includes: an elastic member; and a fiber member configured to be adhered to the elastic member and slidingly contact the shaft. The elastic member is configured to press the shaft to such an extent that fibers of the fiber member are pressed and compressed.
