ABSTRACT:
A photoconductor for electrophotography prepared by forming a carrier generation layer made from an organic photoconducting material on a conductive substrate and further forming a carrier transport layer on the carrier generation layer wherein the organic photoconducting material has a basic structure corresponding to phthalocyanine having the following general formula: ##STR1## wherein a central metal Me is selected from the group consisting of indium, gallium and aluminum, and X is a combined halogen, and the above phthalocyanine is the one in which some hydrogen of benzene rings positioned around the phthalocyanine ring of the above basic structure are substituted by the same halogen with the combined halogen, and furthermore the above organic photoconducting material may be a mixture of the former phthalocyanine and the latter phthalocyanine.
