Abstract

PURPOSE: To provide the device which is stable over a long period of time by so constructing the device that the bristle ends of the brush of the cleaning device lightly contact the inside wall surface of a housing containing the brush and that a spiral bristle-free groove is formed on the brush surface.
CONSTITUTION: When the bristle ends of the brush 7'B for removing the residual toner 13 on a photosensitive drum 1 are lightly contacted to the inside wall surface of a housing 7'A, the brush 7'B cleans the drum 1 and also cleans the inside wall surface of the housing 7'A and therefore no toner layer will be formed on the housing 7'A. With this constitution, a spiral groove 7c is formed in order to prevent degrading of flow of air in the housing 7'A, by which the floating toner is readily discharged outside the cleaning device 7', and the cleaning device which is stable for a long period of time is provided.
