Abstract
A charge generation material for an electrophotographic photoconductor includes a titanyloxyphthalocyanine molecular aggregate. The titanyloxyphthalocyanine molecular aggregate contains between 0.006 to 1.000 water molecules per titanyloxyphthalocyanine molecule. The titanyloxyphthalocyanine molecular aggregate exhibits an X-ray diffraction spectrum, measured using CuK.alpha. radiation, having clear peaks at angles of 7.2.degree., 9.6.degree., 11.6.degree., 13.4.degree., 14.9.degree., 18.3.degree., 23.6.degree., 24.1.degree. and 27.3.degree., the peak at 9.6.degree. being the highest, the spectrum lacking a peak at 26.3.degree., and the angles being 2 .theta..+-.0.2.degree., where .theta. is a diffraction angle. A function-separation-type electrophotographic photoconductor includes the titanyloxyphthalocyanine molecular aggregate of the present invention in the charge generation layer. A monolayer-type electrophotographic photoconductor includes the titanyloxyphthalocyanine molecular aggregate of the present invention in the photoconductive layer.
