PROBLEM TO BE SOLVED: To attain a waste toner recovering path without impeding the versatility of a layout in an image forming device. SOLUTION: Unfixed toner collected by cleaning parts 11 and 13 is recovered to a single waste toner recovering box 17 through carrying paths 14, 16, 21 and 22. Each toner collected from the cleaning parts 11 and 13 is carried through an independent carrying path, so that each other's confluence part does not exist. Further, the carrying means 22 consists of a pipe having curved parts R1 and R2 and a coil auger incorporated in the pipe. The curve radius of the curved part R1 nearer to a power transmission side (the side of a sear 24) is larger than that of the other curved part R2, out of the curved parts R1 and R2. By the relation of such a curved part, a load to an auger can be reduced to prevent its rupture. |
