Patent ID: 7163772

Claim:
An organic electrophotographic photo-receptor having a conductive substrate and a photosensitive layer laid on the conductive substrate, wherein the photosensitive layer contains a μ-oxo bridged heterometal phthalo/phthalocyanine compound represented by the following formula I as a charge generating material: wherein M1 represents a metal atom which is able to have a valence of up to three, M2 represents a metal atom which is able to have a valence of four or five, R each independently represents one or more substituent groups and/or substituent atoms, (A m− ) represents a counteranion A having a valence of m, n/m represents the number of the counteranion, n represents an integer selected from 0 or 1 to 3 corresponding to a valence of M2, and m represents 1 or 2.
