PURPOSE:To prevent the electrification potential of a photosensitive body from being decreased due to destaticization, by providing a surface potential dropping means for allowing a grounded conductive object to contact the surface of the photosensitive body, before the next electrification after each transfer, and destaticizing means by an AC corona discharge. CONSTITUTION:A photosensitive body 2 is charged to the surface by an electrification charger 3, and thereafter, exposed by a lamp 4, and an electrostatic latent image is generated. The electrostatic latent image is developed by a developer 15, and thereafter, transferred to a transfer material 16 by a transfer charger 17. The powder developer 15 which has been left in the photosensitive body 2 is eliminated by a cleaning blade 18 made of urethane having an insulating property. Subsequently, the photosensitive body 2 allows the charge of the surface to escape before destaticization by a conductive means 20. Next, the surface of the photosensitive body is exposed to a corona discharge by an AC corona discharge use charger 22, and also, destaticizes the surface potential to 10V. Also, since no exposure is executed at the time of destaticization, a decrease of the potential at the time of the next electrification scarcely occurs. |
