ABSTRACT:
An electrophotographic photoreceptor comprising a conductive substrate having thereon a photosensitive layer comprising a binder resin having dispersed therein a phthalocyanine composition is disclosed, in which said binder resin is a curing fluorine resin, and said phthalocyanine composition comprises (A) an unsubstituted phthalocyanine compound and (B) a phthalocyanine derivative having a halogen atom(s) and/or electron attractive group(s) at the benzene nuclei, such that the ratio of the number of the halogen atom(s) and/or electron attractive group(s) to the total number of the phthalocyanine units in (A) and (B) is from 0.001 to 0.5. The photoreceptor has a low threshold value of photosensitive characteristics and exhibits high sensitivity in a digital behavior. Besides applicable to a digital recording system, the photoreceptor, when applied to a conventional PPC system, provides a sharp-edged high quality image.
