PROBLEM TO BE SOLVED: To provide a driving device for rotating body and an image forming device using the driving device, by which a high-quality image can be formed at a low cost by preventing the image quality from being deteriorated because irregular rotation is amplified to remarkably cause an image jitter or the vibration of the meshing frequency of an idler gear is amplified and transmitted to the rotating body even in the case of adopting a mechanical reduction gear. SOLUTION: At least one of several gears for transmitting driving force from a driving motor to the rotating body for forming an image is constituted of multiple gears 2-1, 2-2, 3-1 and 3-2 in which a plurality of gears different in diameter are coaxially arranged. The respective module and the number of tooth of the large gears and the small gears of the gears 2-1, 2-2, 3-1 and 3-2 are made different from each other. |
