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 DEG , 9.6 DEG , 11.6 DEG , 13.4 DEG , 14.9 DEG , 18.3 DEG , 23.6 DEG , 24.1 DEG and 27.3 DEG , the peak at 9.6 DEG being the highest, the spectrum lacking a peak at 26.3 DEG , and the angles being 2 theta +/-0.2 DEG , 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.
