ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPH

摘要

An electrophotographic photoreceptor having an excellent repetition stability and an excellent environment characteristic and including a conductive substrate on which the defects are covered without marring its excellent electrophotographic characteristics. The electrophotographic photoreceptor has a conductive support and a photosensitive layer formed over the conductive support, with an under coat layer interposed therebetween. The electrophotographic photoreceptor is characterized in that the under coat layer contains a polyimide resin, and the photosensitive layer contains, as a charge generating agent, oxytitanium phthalocyanine the X-ray diffraction spectrum of which shows main diffraction peak intensities at the Bragg angle (2theta±0.2°) 7.5° and 28.6° when measured using CuKalpha as the radiation source.
