Abstract:
1. An electrophotographic photoreceptor, comprising an electroconductive substrate, a charge transport layer, and a charge generation layer formed on the substrate, wherein: the charge transport layer comprises a charge transport material represented by formula (1) and a binder resin, and the mass ratio of the charge transport material to the binder resin is from 5/100 to 45/100: Ar each of Ar n is an integer of from 3 to 6; the charge generation layer comprises oxytitanium phthalocyanine, such that the oxytitanium phthalocyanine is crystalline oxytitanium phthalocyanine showing peaks at Bragg angles (2θ±0.2°) of 9.5°, 24.1° and 27.3° in an X-ray diffraction spectrum by CuKα ray; and the electrophotographic photoreceptor has a half decay exposure in a range of from 0.089 to 0.096 (μJ/cm
