Abstract
PURPOSE: To make 2-color recording sharply and easily, by providing 2 kinds of photoconductive layers capable of accepting and retaining charges different in polarity from each other.
CONSTITUTION: First photoconductive layer 3, 3' made of an Se, Se-Te, or Se-As type photoconductor having sensitivity to color light B transmitted by the second photoconductive layer 4, and layer 4 consisting chiefly of a eutectic complex salt of a pyrylium type dye and an electrically insulating polymer, and of a silicone oil, and having sensitivity to color light A and transmitting the other light are formed on conductive substrate 2 to prepare a composite electrophotographic receptor. The receptor undergoes the primary charging (a), next, the secondary charging reverse to (a) in polarity and simultaneous or subsequent uniform exposure to color light A (b), and then, exposure to the light image of the 2-color original (c), resulting in forming an electrostatic latent image consisting of color A and black parts, reverse to each other in polarity, and thus, a 2-color sharp copy can be obtained by developing this image with 2-color toners.
