PROBLEM TO BE SOLVED: To provide an image forming device where change in rotation of a rotating body such as a photoreceptor drum can be kept down. SOLUTION: In this image forming device, unevenness in rotation of a photoreceptor drum 4 can be detected based on a detected result of an encoder 18. In this case, when speed of the photoreceptor 4 is increased, driving force of an auxiliary driving motor 19 is weakened and adjusted based on the detected result above so that load is made greater compared to driving force of the photoreceptor drum 4. When the speed of the photoreceptor drum 4 is decreased, the driving force of the auxiliary driving motor 19 is made greater and adjusted so that the load is made smaller compared to the driving force of the photoreceptor drum 4. Thus, the unevenness in rotational speed can be suppressed. |
