PURPOSE:To realize stable separating performance, and to prevent the disorder of transferred toner on transfer paper while improving the transfer efficiency of toner with regard to an electrostatic separating method which employs constant- current transfer and constant-current (difference) separation. CONSTITUTION:A photosensitve drum 1 rotates as shown by the arrow, and the surface is charged uniformly by a primary charger 2 and then irradiated with an optical image 3 to form an electrostatic latent image, which is developed by a developing device 4. Through the operation of the 1st charger 5 and 2nd charger 7 of the developing device, the developed image is transferred onto transfer paper 10 conveyed by a transfer guide 6 and the transfer paper is separated from the photosensitive drum 1 through the operation of the 3rd charger 8. The surface of the photosensitive drum 1 is cleaned with a cleaner 9 and returns to a primary charger 2, thus repeating copying operation. |
