<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor capable of corresponding to a small-sized diameter and a high speed process, having high sensitivity and high photoresponsivity in a long wavelength region and high stability without degradation of electrical properties for repeated use. <P>SOLUTION: An electrophotographic photoreceptor has a conductive support and a photosensitive layer. The photosensitive layer comprises: a binder resin; a charge generating agent; and a charge transporting agent having a cyclopentene isoindoline skeleton. The charge generating agent has a maximum diffraction peak at a Bragg angle of 27.2° with a coincidental peak at 28.6° of which intensity is less than 20% of the intensity of the peak at 27.2° in an X-ray diffraction spectrum using a CuKα radiation source, and contains oxytitanium phthalocyanine that has a diffraction peak at 7.3° in a lowest angle side and no peak in the range from 7.4° to less than 9.4°. <P>COPYRIGHT: (C)2012,JPO&INPIT |
