PROBLEM TO BE SOLVED: To provide an image forming device capable of forming an image with high accuracy and high precision by reducing rotation unevenness by a constitution where transmission delay is reduced at the driving system of a photoreceptor. SOLUTION: Since gear parts 2 are formed at one part of at least one pair of mutually meshing gears out of respective gears constituting the driving system of the photoreceptor in a width direction and vibration proofing gears 1 where the roller part 3 of a specified radius is formed in a remaining part are used, roller parts 3 mainly perform rotation driving transmission made by frictional transmission with each other at a normal time by the mutual meshing of the vibration proofing gears 1, so that vibration caused by the meshing impact of the gears is eliminated, and the rotation unevenness is reduced. On the other hand, the gear parts 2 mainly perform the rotation driving transmission made by meshing transmission at the time of slipping with each other, so that the transmission delay is reduced. |
