PROBLEM TO BE SOLVED: To prevent an image defect or the like caused by the image flowing as a result that paper dust is kept to be stuck on a photoreceptor surface, in the case of adopting cleaner-less system recovering residual toner on a photoreceptor by a developing device. SOLUTION: This image forming device is provided with plural image forming unit Pa, Pb, Pc and Pd along the traveling direction of an intermediate transfer belt 5, and primary transfer part 21a, 21b, 21c and 21d are respectively formed along the intermediate transfer belt 5, and moreover the secondary transfer part 11 is formed on the downstream side thereof. The belt cleaning device 18 provided with a fur brush 20 being normally in contact with the surface on the belt 5 as the paper dust removing member, on the downstream side of the secondary transfer part 11 in the belt traveling direction, and on the upstream side of the primary transfer part 21a on the most upstream side. |
