Abstract
An electrophotographic photoreceptor comprising at least a photosensitive layer formed by laminating a charge generation layer containing a charge generation material and a charge transport layer containing a charge transport material in this order, on a conductive support, wherein the charge generation layer contains an oxotitanylphthalocyanine as the charge generation material and metal oxide microparticles, and the electrophotographic photoreceptor has photosensitive properties in light source of wavelength range from 360 to 420 nm.
Claims10
After the word “nm” and before the period, insert the limitation “wherein the oxotitanylphthalocyanine is an unsubstituted oxotitanylphthalocyanine having a specified crystal type which has a maximum diffraction peak at a bragg angle (2θ±0.2°) of 9.4° or 9.7° in an X-ray diffraction spectrum and has diffraction peaks at bragg angles of, at least, 7.3°, 9.4°, 9.7° and 27.3°”.
