    摘要: An image forming device for printing images on sheets of material includes a photosensitive member for carrying a latent image thereon, a developing roller rotatably disposed adjacent to the photosensitive member for supplying a layer of toner to the photosensitive member through rotation, and a developing blade adjustably disposed adjacent to the developing roller for regulating the thickness of the toner layer supplied to the photosensitive member. A driving circuit controllably rotates the developing roller, and a controller controls the driving circuit. The controller generates signals to control the driving circuit to reverse the rotation of the developing roller under certain conditions.
