An image forming apparatus includes a photosensitive member, a developing unit which is removably installed in a body of the image forming apparatus, a shutter covering a developing region of the photosensitive member when the developing unit is removed from the body of the image forming apparatus and a cleaning member capable of cleaning the surface of the photosensitive member in accordance with rotation of the photosensitive member by making contact with the photosensitive member in conjunction with the shutter covering operation, but which does not contact the photosensitive member when the shutter is open. During a control operation, foreign matter such as used developer adhered to the photosensitive member is removed when the photosensitive member is rotated with the shutter closed.
