ABSTRACT:
An electrophotographic photoreceptor and a method for producing the same are disclosed, in which stability of coating solution of a photoreceptive layer is improved. The photoreceptor comprises a conductive support having thereon a photoreceptive layer containing a binder, a titanylphthalocyanine which has a peak in X-ray diffraction spectrum thereof by Cu-K.alpha. ray at a Bragg angle 2.theta. of 27.2.degree..+-.0.2.degree., and a phthalocyanine derivative formed by reaction of phthalocyanine and a titanium compound represented by the following formula I or II; ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each a group capable of releasing upon reaction with said phthalocyanine.
