ABSTRACT:
A complex type electrophotographic plate comprising an electroconductive support and a charge generating layer and a charge transport layer characterized in that the charge generating layer contains at least a copper phthalocyanine and the charge transport layer contains at least a trinitrofluorenone, has excellent photosensitivity and adhesion to the support. There is also provided an electrophotographic method comprising a first step of charging an electrophotographic plate, a second step of exposing the electrophotographic plate to light and a third step of developing an electrostatic latent image formed on the electrophotographic plate directly or the electrostatic latent image transferred to a recording medium, characterized by using in the first step, as the electrophotographic plate, a complex type electrophotographic plate having a charge generating layer containing at least a copper phthalocyanine and a charge transport layer containing at least a nitrofluorenone and charging said electrophotographic plate positively with excellent recording properties.
