PURPOSE: To reudce unevenness of revolving speeds of image carrires by arranging respective flywheels so that parts being adjacent each other of respective flywheels provided at supporting shafts of respective carriers overlap each other in the axial directions of image carriers. CONSTITUTION: Circular flywheels for reducing unevenness of rovolving speeds 21BK, 21M. 21Y, 21C are respectively integrally fitted to respective supportng shafts 11BK to 11C and fixed to respective shafts 11BK, 11M, 11Y, 11C in concentric shapes. Moreover, respective flywheels 21BK, 21M, 21Y, 21C are arranged so that parts being adjacent each other of respective flywheels 21BK, 21M, 21Y, 21C overlap each other in the axial directions of photoreceptors 10BK, 10M, 10Y,10C. That is flywheels 21BK, 21M, 21Y, 21C being adjacet each other are positioned by being away from each other without interfering each other in such a manner that they shift their positions each other and they overlap each other in the axial directions of supporting shafts 11BK to 11C. |
