Title: Metal oxide particle supporting organic pigment, method for producing the same, electrophotographic photoreceptor and pigment ink composition containing the same
Inventor: ARIGA TAMOTSU
IPC: C09D11/52
Filed: 2000-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor having high abrasion resistance and excellent electric characteristics. SOLUTION: In this electrophotographic photoreceptor in which an under- coating layer 2, a charge generation layer 31, a charge transportation layer 32 and a protective layer 4 are laminated to an electroconductive substrate 1 in this order, a solution comprising metal oxide particles supporting titanyl phthalocyanine pigment as a charge generation material on the surface of titanium oxide particles is used as a coating solution of the protective layer. In this case, the coating solution of the protective layer is obtained by dissolving a polycarbonate and a fixed charge transportation substance in tetrahydrofuran with mixing to give a solution and by dispersing the organic pigment supporting titanium oxide particles into the solution.  Consequently, the abrasion resistance of the photoreceptor is dramatically increased and electric characteristics are improved (residual potential is reduced).
