PROBLEM TO BE SOLVED: To improve the cleaning function, and to prevent the soiling of a device inside or an image on recording paper by providing a cover for intercepting toner scattering on a sheet state member side, from a diameter changing section of a transporting screw to the side of a large diameter section in the vicinity on the upstream side in the toner transporting direction. SOLUTION: This cleaning device respectively arranges by disposing the screw large diameter section 20a in a casing, and the screw small diameter section 20b so as to project outside the casing through a penetrating hole 16d provided on a side plate 16c. Moreover, a cover 16e in a circular-arc shape is provided so as to project inward in a specific range, on the side plate 16c inside surface and in the periphery of the penetrating hole 16d. Namely, the circular-arc shape cover 16e is disposed so as to cover the side of the screw large diameter section 20a in the toner transporting direction on the upstream side vicinity from the diameter changing section 20c of the transporting screw 20. The side position on which the circular-arc shape cover 116e is, the position for intercepting a scattering path of the toner scattering from the vicinity of the diameter changing section 20c to a scraper by the rotation of the transporting screw 20. |
