Abstract
An image forming apparatus includes: a development unit that develops an electrostatic latent image on an image bearing member and is demountable from a main body of the apparatus; a developer bearing member that is provided in the development unit and supplies a developer it bears to the image bearing member; a motor that drives the developer bearing member to rotate; and a control portion that allows the motor to rotate in a first rotation direction and in a second rotation direction reverse to the first rotation direction. During image formation, the control portion rotates the motor in the first rotation direction, and when a replacement mode is set in which the development unit is demounted from the apparatus main body so as to be replaced, the control portion rotates the motor in the second rotation direction so that the developer bearing member is rotated by a predetermined amount in a direction reverse to a direction in which the developer bearing member is rotated during the image formation.
