PROBLEM TO BE SOLVED: To prevent an image noise owing to condensate from occurring by restraining generation of the condensate by changing the recycle feeding ratio of toner in accordance with a transporting load on means for transporting the toner recovered by a cleaning device to the developing device, or the waste toner container, with respect to the image forming device. SOLUTION: Relating to this image forming device the toner recovered by the cleaning device is transported into the waste toner container 12 by first transporting means 8A, or into the developing device by second transporting means 8B, to detect the torque of a transporting motor at the time, and to control the recycle toner feeding ratio, in accordance therewith. Since the detection result of the transporting load results in a matter corresponding to flow property, in other words, corresponding to lowering state of the recycled toner, when the transporting load rose, the generation of the condensate is restrained by reducing the recycled toner feeding ratio. |
