摘要:
An electrophotographic photoreceptor including an electroconductive substrate, a charge generation layer overlying the electroconductive substrate to generate a first charge to form an electrostatic latent image when exposed to a first light, and a charge generation and transport layer overlying the charge generation layer to generate a second charge when exposed to second light and to transport the first and second charges to a surface of the photoreceptor.
