Abstract:
An electrophotographic photoreceptor includes a conductive substrate; and a photosensitive layer arranged on the conductive substrate and containing, as a charge generating material, any one material selected from the group consisting of titanyl phthalocyanines, metal-free phthalocyanines, chlorogallium phthalocyanines and hydroxygallium phthalocyanines; and, as an electron transporting material, a naphthalene tetracarboxylic acid diimide compound represented by Formula (1) below, where R 1  and R 2  each represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an alkylene group, an alkoxy group, an alkyl ester group, a phenyl group optionally having a substituent, a naphthyl group optionally having a substituent, or a halogen element; and R 1  and R 2  are optionally the same or different: The photoreceptor realizes a stable print density even in a low-temperature environment by suppressing a reduction in print density that is caused by potential fluctuation of the photoreceptor in the low-temperature environment.

Claim (Index 2):
The electrophotographic photoreceptor according to  claim 1 , wherein the photosensitive layer is a laminate-type positively-chargeable photosensitive layer in which a charge transport layer, containing at least a hole transporting material and a resin binder, and a charge generation layer, containing at least the charge generating material, a hole transporting material, the electron transporting material and a resin binder, are sequentially laminated.
