PURPOSE: To provide an image forming device which withstands a long term use, achieves the miniaturization of a cleaning device and is free of waste toner. CONSTITUTION: This device is composed of a cleaning roller, to which a bias having the opposite polarity of toner 10 remaining on a photoreceptor 1 is applied, a member for promoting the opposite electrification of the toner, an electrifier 2, which makes the electrification polarity of the toner 10 the same as that of the surface of the photoreceptor 1, and a developing roller 4, to which a bias voltage capable of recovering the toner 10 on the photoreceptor 1 is applied. Thus, since the device can comprise the simplified cleaner which is free from waste toner, and also the toner is emitted from the cleaner at the same time as an image forming operation, cleaning performance is not easily deteriorated and the device withstands a long term use. |
