Method of manufacturing organic photoconductor for electrophotography

摘要

A charge generation layer and a method of manufacturing a charge generation layer of a highly sensitive organic photoconductor for electrophotography is provided, wherein the charge generation layer is formed by using a dispersion liquid in which an organic pigment or dye is so dispersed as to be fully utilized as a charge generation agent. The organic pigment or dye is dispersed and pulverized in a dispersing solvent, with ball-shaped pulverizing media of about 0.1 to about 0.3 mm in diameter, to an average particle size of from about 0.1 to about 0.3 mu m. The ratio of the organic pigment or dye to the solid components of the dispersion liquid is set at about 5 to about 95 weight %. The ball-shaped pulverizing media are removed from the dispersion liquid prior to dip coat formation of the charge generation layer. The total weight of the ball-shaped pulverizing media is set at about 0.25 to about 5 times as heavy as the weight of the dispersion liquid.
