Electrophotographic photoconductor using aluminum phthalocyanine compound in charge generating layer
 This invention relates to a layered photoconductor having a charge generating layer and a charge transfer layer superimposed on an electroconductive substrate, which photoconductor has as the main component of the charge generating layer an aluminum phthalocyanine derivative which is represented by the formula, AlC.sub.32 N.sub.8 H(17-x)Cl.sub.x (wherein x=1.0 to 3.0), has the loss of weight on heating of 6.+-.0.5% by weight, shows strong X-ray diffraction peaks at 6.7 degrees, 11.2 degrees, 16.7 degrees, and 25.6 degrees, and shows the maximum absorption of the visible absorption spectrum in a wavelength range of 640 nm to 660 nm or 750 nm to 850 nm. The photoconductor according to this invention is highly sensitive without suffering from dispersion of performance, exhibits high sensitivity in various ranges of wavelength, and does not cause fogging in actual printing.
