Abstract
The invention relates to a double-layered electrophotographic photoreceptor comprising a conductive support, a carrier generation layer provided on the conductive support, and a carrier transport layer provided on the carrier generation layer. The carrier generation layer contains a generation material, which generates carrier upon absorption of light, and a compound having an epoxy group. The carrier transport layer contains a carrier transport material which transports the generated carrier. This photoreceptor has excellent pre-exposure properties and durability for repeated use.
