Abstract

PURPOSE:To obtain a copy of clean background part by providing a toner remover and so constituting the same that only the toner stuck on the background part of the surface of a photoreceptor is removed. CONSTITUTION:A photoreceptor 7 rotates in the direction of an arrow and is charged to + by a charge Corotron 9. Latent images are formed by exposure 10, and the toner images are formed on the photoreceptor 7 by a developing device 8. These images are transferred by a transfer Corotron 11, and are fixed, whereby a copy is made. A toner remover 13 is provided with a charging means and consists of a Corotron 1 charging a moving member 3 uniformly and a Corotron 2 destaticizing the moving member 3. In the developing device 8, the carrier is charged to + and the toner to - and therefore, the toner of - corresponding to the magnitude of the potential difference between the surface voltage of the photoreceptor 7 and the applied voltage of the developing device 8 is developed on the surface of the photoreceptor 7. As the developer degrades, the toner of + sticks on the background part, but the stuck toner is adsorbed and removed by the moving member 3 charged to -.
