ABSTRACT:
The present invention drives cleaning member moving devices for moving cleaning members of a plurality of chargers at the same time by a single cleaning motor to miniaturize an image forming apparatus and reduce the cost. Further, at the end time of cleaning, all the cleaning members are shifted to a predetermined area by the cleaning member moving devices, and the cleaning motor is stopped, thus the cleaning members remain in a charging area, and uneven charging is prevented.
