METHOD FOR REFINING MATERIAL OF ELECTRONIC PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for refining a material of electronic products by which an electric charge transferring material for electrophotography can be mass-produced, electrical characteristics such as good sensitivity and residual potential are ensured and a material not containing impurities which deteriorate electrical characteristics and having satisfactory electrical characteristics is obtained so as to obtain an electrophotographic photoreceptor less liable to a change of characteristics in fatigue. SOLUTION: In the method for refining a material of an electronic item, the material or its intermediate is dissolved in an organic solvent and the resulting solution is brought into contact with activated clay at 65-200 deg.C to enhance the electrical characteristics of the material.
