This invention provides an optical semiconductor material comprising: (1) a noncrystalline titanium phthalocyanine compound which does not show substantial X-ray diffraction peak in X-ray diffraction chart, (2) a pseudo-noncrystalline titanium phthalocyanine compound which shows broad X-ray diffraction peaks at Bragg angles of 6.9.degree., 15.5.degree., 23.4.degree. and 25.5.degree. measured by using CuK.alpha. beam and (3) an assembly of said noncrystalline titanium phthalocyanine compound and pseudo-noncrystalline titanium phthalocyanine compound. Further, this invention provides an electrophotographic plate comprising an electrically conductive substrate, and a charge-generating layer and charge-transferring layer on the electrically conductive substrate, characterized in that the charge-generating layer contains the above noncrystalline and/or pseudo-noncrystalline titanium phthalocyanine compound(s).
