PROBLEM TO BE SOLVED: To make setting of inertia mass possible to be arranged for preventing rotary unevenness amplification of a driving motor, in the case of using as plural independent driving devices at plural driving speed in an image forming device, and to enable reducing such as the number of components. SOLUTION: By this image forming device of such as a copying machine performing record of the image by forming the image on a photoreceptor 1 in repeating respective processing stage of electrifying, writing, developing, transferring, cleaning, discharging or the like, and transferring the image on a paper sheet, in the case of using as the plural independent driving devices at the plural driving speed, the rotary speed of the driving motor 10 is made to coincide with the rotary speed of the higher speed side by changing the number of gear teeth on the output gear 13 of the driving motor 10 provided with the least teeth number. |
