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 member to contact the surface of the photosensitive body, before the next electrification after each transfer, and a uniform exposing means for destaticization. CONSTITUTION:A photosensitive body 2 is charged to the surface by an electrification character 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 photosensitive body is exposed uniformly by an exposing lamp 22, and also, the surface potential is destaticized to 20V. In this way, a decrease of the potential at the time of the next electrification can be suppressed to 20%. In this case, as for the conductive means, in addition to a conductive rubber roller, conductive blade, rod, brush, etc., can be used. |
