PREPARATION METHOD OF DISPERSION FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a preparation method of a dispersion for an electrophotographic photoreceptor by which the dispersion can be suppressed from turning into unstable by aggregation of a pigment and the degradation of a liquid recovery ratio upon dispersion can be suppressed, and to provide a method for manufacturing an electrophotographic photoreceptor using the dispersion for the electrophotographic photoreceptor. SOLUTION: The preparation method of the dispersion for the electrophotographic photoreceptor is characterized by dispersing a gelled polyamide resin including an organic pigment in a solvent by use of a dispersion medium. The method for manufacturing the electrophotographic photoreceptor including an undercoat layer and a photosensitive layer in this order on a substrate is characterized by forming the undercoat layer by using the above dispersion for the electrophotographic photoreceptor.
