PURPOSE:To prevent the generation of a poor copying and a reverse printed image, in a constant current control contact copying. CONSTITUTION:In an electrophotography device provided with a sensitizer 9; a means 1 to charge the sensitizer 9; an exposing means to project an image beam to the charged surface of the sensitizer, and to form an electrostatic laminent image; a developing means 3 to make the static laminent image to a sensible image; a copying means 5a to pressure contact to the sensitizer 9 through a copying member 12; and a copy bias applying means 51 to apply a copy bias to static adsorb the sensitible image to the copying means 5a by a constant current control; an optical power removing means 4 to remove the static charge of the area of the sensitizer 9 except for the area to copy to the copying member 12, is provided between the developing means 3 and the copying means 5a, and such a constitution is the specific feature of this device. |
