PROBLEM TO BE SOLVED: To provide an image forming apparatus in which the uneven rotation of a photoreceptor due to the influence of a molded gear and the reinforcing rib of a pulley is prevented. SOLUTION: The frequency by the rib interval of the gears (101, 102 and 103) and the pulleys (104 and 105) obtained until the photoreceptor (4) is driven and the frequency of one rotation of the gear (101) formed on an output shaft coaxial to a main motor (1) and the main motor (1) are unified to nearly the same frequency by considering the shape of the rib respectively, so that the uneven rotation of the photoreceptor (4) is prevented from being caused with a plurality of frequencies. Furthermore, the uneven rotation of the photoreceptor (4) is reduced all the more by providing an optimized fly wheel (5) coaxially to the photoreceptor (4). |
