ABSTRACT:
The improved photoreceptor has a light-sensitive layer that contains as carrier generation materials both a polycylic quinone compound selected from among specified anthanthrone pigments, dibenzpyrene pigments and pyranthrone pigments and a specified bisazo pigment, and that also contains a specified stilbene compound as a carrier transport material. This photoreceptor has good spectral sensitivity characteristics over a broad range of wavelengths, has high sensitivity, has a long cycle life on account of reduced residual potential, is adapted for fast copying processes, and is capable of copying red images with improved fidelity of reproduction.
