Abstract
PURPOSE: To attempt to eliminate the remaining potential at all and improve the transfer efficiency by making an insulating layer on the photoconductive layer of a special photoconductive material.
CONSTITUTION: Photoconductive layer 2, such as, Se is provided on the electroconductive substrate 1, and (semi) transparent photoconductive layer 3 which is of a different transmitting type and of less than 1/10 relating to its photosensitivity as compared with the layer 2 is disposed on the layer 2. This photoreceptor is uniformly and positively on its surface by charger 4 and the exposure of photoimage is made by slit exposure combined with charger 5. At the same time it is subjected to AC corona to be destaticized. Next, after the electrostatic image contrast has been enhanced by the whole face exposure, it is positive-positive developed by developing agent 6. Next, the whole surface is exposed to an intense visible light. The electrostatic image is eliminated via photoconductivity of the layer 3 which has functioned as the insulating layer up to that time, and the image is transferred onto transfer material 7. In consequence such a weak voltage as 500 V will do for the outer electric field which has required the voltage of electric power 8 more than 200 V.
