Abstract
An image forming apparatus includes: an image carrier; a latent image forming device; a developing device; an electrode which faces to the image carrier; an electric power source, a toner contamination detecting device for detecting toner contamination onto the electrode; an electrode cleaning device for cleaning the electrode; and a controlling section. The control section controls the electric power source to apply at least an alternating current voltage to the electrode so that toner image is rearranged by reciprocally moving toner of the toner image between the image carrier and the electrode control section and allows the electrode cleaning device to clean the electrode when the toner contamination detecting device detects toner contamination on the electrode, and performs the toner rearrangement by the electrode from which the toner contamination is removed.
