PROBLEM TO BE SOLVED: To provide an image forming device in which a developing gap between an image carrier and a developer carrier is extremely highly accurately adjusted. SOLUTION: A rotatable roller 200 abuts on a supporting shaft 119 partially projected from bearings 151a and 154a. The roller 200 is pressed with elastic force with which the supporting shaft 119 is pressed by the elastic force of a taut coil spring 202 laid over an arm 201 and a supporting panel 18. Thus, since the supporting shaft 119 of a revolver developing device 100 is biased by the pressing of the roller 200, a backlash component between the supporting shaft 119 and the bearing 154a is eliminated, and the fluctuation of the supporting shaft 119 at a rotating time is eliminated, so that the developing gap G is extremely highly accurately adjusted. |
