Abstract
PURPOSE: To eliminate image disturbances and transfer unevenness generated at the transfer of conductive toner by providing a slit member in the shield plate opening part of a coroner discharger for transfer and controlling corona radiation.
CONSTITUTION: The electrostatic latent images formed on the surface of a drum 11 are developed 14 by conductive toner Tn and AC corona radiation 17 is accomplished to the drum 11. Next, in order to transfer the toner images on the drum 11 to the surface of transfer paper P, DC corona discharging 18 is accomplished on the back surface of the transfer paper P. The corona wire 31 of the discharger 18 is encircled from 3 sides by a shield plate 32 and the slit plate 33 composed of insulating material for defining the radiation region of the corona radiated toward the back surface of the transfer paper P is provided to the opening part of the plate 32 opposing to the drum 11. A slit for corona passage is provided in the lengthwise direction of the discharger to the plate 33 and controls the corona radiation.
