ABSTRACT:
A removal nip having a predetermined width is formed by a sweep roller pressurizing mechanism, which adjusts the length of a tension spring by rotating an adjustment screw, and adjusting the size of an energizing force of a sweep roller with respect to a photosensitive drum. A pressurizing mechanism similar to the sweep roller pressurizing mechanism is also provided in a developing roller, to adjust the energizing force of the developing roller, to thereby form a developing nip having a predetermined width.
