  • Combination Of More Than One Step In Electrophotography (AREA)

Abstract

PURPOSE: To make possible providing of charging function and destaticizing function in combination and obtain the electrophotographic apparatus of the simple constitution by applying positive and opposite polarities to a corona discharger during the time of more than two turns of a photosensitive drum.
CONSTITUTION: Voltage by a corona discharge 2 is applied on a photoreceptor drum 1, thence the electrostatic latent images corresponding to the original 4 are formed. When the photosensitive drum having undergone transfer opposes to the discharger 2 in the second turn, the voltage of opposite polarity is applied to the discharge 2, whereby the charges of the drum surface are surely removed. Hance, the corona discharger 2 is able to provide charging function and destaticizing function selectively, resulting in less number to parts and simpler constitution of the copying apparatus.
