ABSTRACT:
In a cleaning unit for a copying apparatus wherein a part of the photoreceptive drum and adjacent cleaning unit can be exposed by moving a movable part of the copying apparatus in a direction of movement at a right angle to the axis of the photoreceptive drum. This movement allows a main charger installed in the cleaning unit to be integrally loaded into and unloaded from the copying apparatus together with the cleaning unit. The cleaning unit can be opened in the state of being secured to the copying apparatus by rotating it in a direction away from the photoreceptive drum, and the main charger secured to the cleaning unit can also be opened by rotating it in the direction identical to that of the cleaning unit.
