PURPOSE:To make it possible to form easily an electron charge generation layer which is uniform and excellent, by dispersing the electron charge generation material treated with a monomer into a binder resin. CONSTITUTION:The title material is one in which a treatment is performed with a monomer reacting mutually with pigment particles as a electron charge generation material, and the dispersion property into a resin is increased. Phthalocyanine class of pigment has a strong property of electron supply, and forms a weak electron-transfer complex combining with an electron attractive monomer. Therefor, by treating the phthalocyanine pigment particles with the electron attractive monomer, the monomer is made graft on the boundary surface of pigment particles, so that the dispersion property into the binder resin and the adhesion between the pigment particles and the binder resin can be increased. The sensitivity and light resistance of an organic photoconductive material can be increased, thereby.
