Electrophotographic photoconductor using aluminum phthalocyanine compound in charge generating layer

A layered photoconductor comprising a charge generating layer and a charge transfer layer superimposed on an electroconductive substrate, which photoconductor has as the main component of said charge generating layer an aluminum phthalocyanine derivative defined by the following requirements:

• (a) that said derivative is a chlorinated aluminum phthalocyanine represented by the formula, AlC.sub.32 N.sub.8 H.sub.( 17-x)Cl.sub.x (wherein x represents a number in the range of 1.0 to 3.0),
• (b) that the weight on heating (the ratio of weight lost by heating on a thermobalance at a temperature increasing rate of 5.degree. C./min. from 140.degree. to 220.degree. C. to the weight prior to heating) is 6.+-.0.5% by weight,
• (c) that the X-ray diffraction spectrum shows strong diffraction peaks at the Bragg angles of 6.7 degrees, 11.2 degrees, 16.7 degrees, and 25.6 degrees, and
• (d) that the visible absorption spectrum shows the maximum absorption in a wavelength range of 640 nm to 660 nm or 750 nm to 850 nm.
