PURPOSE:To provide an image forming device constituted so that an input shaft disposed on a photoreceptor or one end of a developing roller and an output shaft coupled to a driving part are easily coupled even when the teeth positions thereof are deviated. CONSTITUTION:The input shaft 45 obtained by forming the plural teeth 51 around the shaft center thereof is disposed on the photoreceptor 2 on which load is added or one end of the developing roller. Besides, the device is provided with the output shaft 43 having the plural teeth 49 meshed with the teeth 51 of the shaft 45 on an identical shaft and power transmission parts 54 and 55 mutually coupled to the driving part 53 coupled to a motor and the shaft 43 by leaving prescribed play in a rotating direction. Then, when the positions of the teeth 49 of the shaft 43 and the teeth 51 of the shaft 45 are deviated, the shaft 43 is rotated by light force within a play range with respect to the driving part 53. |
