PROBLEM TO BE SOLVED: To provide an image forming device having a drive transmitting mechanism with a simple structure for making the banding caused by the vibration of a photoreceptor drum when caused in drive transmission inconspicuous. SOLUTION: Photoreceptor shafts 12BK, M, Y, C for holding photoreceptor 11 BK, M, Y, C are held by a side plate 16 so as to be rotatable by a bearing 17, driven-side photoreceptor shaft gears 13BK, M, Y, C fixed to each photoreceptor shaft are arranged alternately in the photoreceptor shaft direction in such a manner as to be rotation-transmittable through idle gears 14a, 14b by the combination of carrying directional odd numbers (first color 13BK and third color 13) or even numbers (second color 13M and fourth color 13C), and the idle gear 14a and the idle gear 14b are arranged on the photoreceptor shaft 12M and on the photoreceptor shaft 12Y so as to be rotatable to each shaft, respectively. The driving force of a motor 21 is transmitted in the route of a drive gear 22 → the photoreceptor shaft gears 13BK, 13B → the idle gears 14a, 14b → the photoreceptor shaft gears 13Y, 13C. |
