Abstract

PURPOSE:To prevent attenuation of the primary latent image accompained to ionic modulation without increasing the number of parts, by periodically varying the bias electric field between the screen-form photoreceptor and the image receiving body, on which the primary and secondary latent images are formed. CONSTITUTION:An ionic current according to the corona electric discharge between the corona wire 10 of the electric discharge apparatus for modulation, and the opposite electrode member 11 is modulated by the primary latent image formed on the photoreceptor screen 1, and the secondary latent image is formed on a copying paper 12 of the image receiving body. In this case, when the bias electric field which is varied by + or -0.05-2kV/mm. at every ionic current modulation extending from once to twenty times is periodically generated between the conductive member 2 of the screen 1, and the surface of the copying paper 12 through the electric power source, not only attenuation of the primary latent image accompanied to the ionic modulation but also fog of a bright part and a density variation of a dark part are prevented, and a picture of good quality can be formed repeatedly.
