Patent ID: 8346130

Claim:
An image forming apparatus configured to form an image on a recording medium with a developer, the image forming apparatus comprising: a photosensitive drum; a developing roller disposed such that a peripheral surface thereof contacts a peripheral surface of the photosensitive drum, the developing roller being configured to supply the developer to the peripheral surface of the photosensitive drum; a rotation controller configured to execute the steps comprising: (a) controlling the photosensitive drum and the developing roller such that the developing roller rotates in a predetermined direction and the photosensitive drum rotates in a forward direction in which a peripheral surface of the photosensitive drum moves in a same direction as the peripheral surface of the developing roller at a contact position where the peripheral surface of the photosensitive drum contacts the peripheral surface of the developing roller; (b) controlling the photosensitive drum and the developing roller, after the step of (a), such that the developing roller continues to rotate in the predetermined direction and the photosensitive drum rotates in a reverse direction which is opposite to the forward direction; (c) controlling the photosensitive drum and the developing roller, after the step of (b), such that the developing roller stops and the photosensitive drum continues to rotate in the reverse direction; and (d) controlling the developing roller, after the step of (c), such that the developing roller restarts to rotate in the predetermined direction.
