ABSTRACT:
A proper frequency of a driving system is shifted to a high frequency side by increasing the rigidity of a photoreceptor drum or the proper frequency of the driving system is shifted to a low frequency side by reducing the rigidity of the photoreceptor drum so that the proper frequency of the driving system is made so as not to conform with a frequency of a speed fluctuation component transmitted to the driving system. With this construction, the photoreceptor drum is prevented from causing the resonance and the speed fluctuation is reduced so that an image quality can be improved.
