Abstract
PURPOSE:To enable stereoscopic characteristic to be copied as well by so arranging the method that the photoreceptor is continuously exposed alternately by A-color light and B-color light with a microspace as a unit, making the polarities of the photoreceptor surface potentials in the exposed parts of the A-color light and the B-color light mutually opposite and visualizing these parts with the toners of two colors. CONSTITUTION:The photoconductive layers 1A, 1B of a photoreceptor 1 are charged in mutually opposite directions. More specifically, these are subjected to primary charging of positive polarity under uniform irradiation of the B-color light, then to the secondary charging of negative polarity in the dark, slightly less than the primary charging. In this state, electric double layers are formed double with opposite directions of dipole moment via the photoconductive layers 1A, 1B, so that the surface potential of the photoreceptor 1 of this time is made 0. If the A-color light and the B-color light are irradiated to the photoreceptor 1 of this time, the photoconductive layer 1A is made conductive in the part irradiated with the A- color light and the photoreceptor surface potential assumes negative polarity. In the part irradiated with the B-color light, the photoconductive layer 1B is made conductive and the photoreceptor surface assumes positive polarity.
