摘要：
A method of modifying a pigment which comprises dissolving the pigment into sulfuric acid and then mixing water with the pigment-sulfuric acid solution. The modified pigment is excellent in achieving uniform dispersion and has a small particle size. An electrophotographic photoreceptor containing the modified pigment as the organic photoconductor has uniform sensitivity, sufficient charge acceptance and small dark decay.
