ABSTRACT:
An electrophotographic photoconductor, includes metal-free phthalocyanine as a charge-generating substance, wherein the X-ray diffraction spectrum of said metal-free phthalocyanine as measured using CuK.alpha. as a radiation source includes intense diffraction peaks at Bragg angles (2.theta..+-.0.2.degree.) of 7.5.degree., 9.0.degree., 16.6.degree., 17.2.degree., 21.5.degree., 22.2.degree., 23.8.degree., and 28.5.degree., and wherein the infrared absorption spectrum of said metal-free phthalocyanine includes four absorption bands with the maximum absorption intensity at a wavenumber of 716 cm.sup.-1 between a wavenumber of 700 cm.sup.-1 and a wavenumber of 760 cm.sup.-1 and a characteristic absorption band at a wavenumber of 3,291.+-.2 cm.sup.-1.
