摘要： PROBLEM TO BE SOLVED: To solve the problems of image deterioration such as jittering and banding caused by a delay for one rotation in correction for a driving pattern, since in the conventional method, it is necessary to frequently correct the driving pattern due to the fact that a variation cycle for photoreceptor peripheral members and rotational variation cycle for the photoreceptor are gradually shifted, though in the conventional technique, offsetting of variation is carried out by a method of applying the inversion waveform of the rotational variation to the driving motor in order to reduce the rotational variation waveform of the photoreceptor; furthermore, the driving patterns to be applied to a driving motor is prepared beforehand so that the rotational variation of the photoreceptor due to load variation to the peripheral members surrounding the photoreceptor is mitigated and switching is carried out according to the situation. SOLUTION: The relationship between a rotational frequency and rocking frequency of photoreceptor peripheral members and rotational frequency of the photoreceptor is made an integral ratio. Furthermore, rotational variation of the photoreceptor is detected and the rotational variation is offset by the inverted driving control of a variation pattern. A good image without any color smearing nor jittering due to rotational unevenness can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
