ABSTRACT:
In an image forming apparatus, while an engaging pawl of a driving unit for driving a cleaner for cleaning a charger performs one reciprocating movement along the charger, an engaging projection of the cleaner engages the engaging pawl. Hence, when the charger is remounted after first detaching it from the image forming apparatus, engagement between the cleaner and the driving unit can be securely performed. As a result, cleaning of the charger can be securely performed after mounting the charger on the image forming apparatus.
