Abstract
Present invention provides an image forming apparatus wherein a photosensitive member is subjected to optimum fatigue treatment in order to prevent the fluctuation of copying density and prevent fogging. Therefore, an image forming apparatus according to the invention is arranged so that the duration of prerotation for subjecting a photosensitive member to the fatigue treatment in advance is regulated in accordance with both the rest time after the completion of a previously-executed copying operation and the current temperature of the photosensitive member.
