Coating solution for charge generation layer and electrophotographic photoreceptor using same

Abstract

Disclosed are a coating solution for forming a charge generation layer, which comprises: (A) a phthalocyanine composition, (B) a binder resin represented by the formula: ##STR1## wherein R represents an alkylene group, R.sup.1 represents an alkyl group; and m, n and k each represent a ratio of recurring unit numbers and are numerals satisfying the relations of k+m+n=1, n>m>0 and 0.3.gtoreq.k.gtoreq.0, (C) at least one of a melamine resin and a benzoguanamine resin in a 1- to 5-fold amount in terms of the weight ratio of the amount of the binder resin, and (D) a solvent having both a hydroxyl group and an ether group in one molecule, and an electrophotographic photoreceptor using the same.
