ABSTRACT:
A layered-form electrophotographic photoreceptor which is composed of a conductive substrate, a charge generating layer (CGL) laid on the conductive substrate, and a charge transporting layer (CTL) laid on the CGL, wherein the CGL includes .mu.-oxo-aluminum phthalocyanine dimer as a charge generating material (CGM), and the CTL comprises a specific hydrazone compound as a charge transporting material (CTM). The electrophotographic photoreceptor shows good stability and electric property (for example, good chargeability, low dark decay, and low residual potential), even if it is employed as a high-gamma photoreceptor which corresponds to a short wavelength light sauce such as LD ray and LED ray.
