Photoconductive organic pigment, photoconductive organic pigment dispersion liquid, electrophotographic photoreceptor and electrophotographic device using the same

摘要

The present invention relates to a photoconductive organic pigment comprising granular cores and an organic pigment having photoconductive properties which organic pigment adheres to the surfaces of the granular cores, a photoconductive organic pigment dispersion liquid comprising the photoconductive organic pigment, and an electrophotographic photoreceptor comprising an electroconductive substrate laminated with a photosensitive layer containing the photoconductive organic pigment and an electrophotographic device using the electrophotographic photoreceptor.
