Abstract
An electrophotographic photoreceptor has a layered-type structure comprising an electrically conductive support having thereon a charge generating layer comprising a charge generating organic material and an electron transportable carrier transport layer comprising an electron transport organic material and a binder, and the electron transport material under a mutual molecular aggregation state of the electron transport material which results in a new adsorption component at 20 nm or more longer wavelength side than the maximum monomoleclar absorption wavelength of the electron transport material is incorporated in the electron transportable carrier transport layer and the weight ratio of the electron transport material to the binder of the electron transportable carrier transport layer ranges from 25/100 to 200/100. According to the foregoing, it is possible to provide an electrophotographic photoreceptor which has a small residual electric potential and can assure an image contrast.
