Abstract
Disclosed is a phthalocyanine composition which comprises having clear diffraction peaks at 17.9.degree., 24.0.degree., 26.2.degree. and 27.2.degree. of Bragg angles (2.theta..+-.0.2.degree.) in an X-ray diffraction spectrum with Cu K.alpha., a process for preparing the same, an electrophotographic photoreceptor using the same and a coating solution for forming a charge generation layer containing the same.
