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 an organic solvent soluble phthalocyanine represented by the following formula I; ##STR1## wherein X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are each an alkyl group, an alkoxy group or a an aryloxy group, these groups each may have a substituent; M is a metal atom; Y is a halogen atom, an oxygen atom, a hydroxy group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, or a siloxy group, these organic groups may have a substituent; k, 1, m and n are each an integer of 0, 1, 2, 3 or 4; and p is an integer of 0, 1 or 2.
