Abstract:
An electrophotographic photosensitive member, comprising a support, and a photosensitive layer formed on the support; said photosensitive layer containing iodogallium phthalocyanine having a crystal form selected from those characterized by X-ray diffraction patterns (a)-(e) shown below respectively obtained by a CuK.alpha. characteristic X-ray diffraction method:(a) having a strongest peak at a Bragg angle (2.theta..+-.0.2 deg.) of 9.6 deg. and free from another peak having an intensity of 30% or more of that of the strongest peak,(b) having a strongest peak and a second strongest peak at Bragg angles (2.theta..+-.0.2 deg.) of 9.4 deg. and 27.1 deg. wherein the second strongest peak has an intensity of at least 30% of that of the strongest peak,(c) having a strongest peak and a second strongest peak at Bragg angles (2.theta..+-.0.2 deg.) of 7.5 deg. and 27.7 deg.,(d) having a strongest peak and a second strongest peak at Bragg angles (2.theta..+-.0.2 deg.) of 7.5 deg. and 26.4 deg., and(e) having two peaks among a strongest peak, a second strongest peak and a third strongest peak at Bragg angles (2.theta..+-.0.2 deg.) of 8.8 deg. and 27.2 deg.
