Abstract:
In a tandem type image formation apparatus, a drum drive unit which always simultaneously drives respective photoreceptor drums, is assembled such that it is possible to synchronize cycles of rotational speed fluctuations of the respective photoreceptor drums in assembling. In this manner, the photoreceptor drums rotate so as to synchronize the cycles of rotational speed fluctuations of the photoreceptor drums even after assembling. Therefore, a phase difference in the cycles of rotational speed fluctuations of the photoreceptor drums is determined, and the photoreceptor drums are assembled so as to be shifted by the phase difference.
