PURPOSE:To prevent generating fogging when continuously forming images by the use of a negative organic photoconductive body by providing a separating device which gives alternating current charges when an image carrier is passing through and that superimposes negative charges onto the alternating current charges when the image carrier is passing through. CONSTITUTION:When positive charges are given by a transfer charger 21 from the back plane of sheet paper, a toner image on a photosensitive body 10 is electrostatically attracted to the sheet paper and is transferred. Then, the sheet paper reaches the separating charger 22. For the separating charger 22, a switch 22a is connected to a direct current power source 22c by a controller and the charges which are the alternating current charges superimposed with the negative charges are given to a part 10a which is a part of the photosensitive body 10 and is positively electrostatically charged by the AC power source 22b and the DC power source 22C. Then, the positive charges on the photosensitive body are neutralized and removed. In such a manner, even when repeatedly copied, the belt-shaped fogging is not generated. |
