摘要： A double-layered positively-charged organic photoreceptor t does not suffer from contamination caused by charge transport compounds that dissolve out during coating of a charge generating layer, and in which the charge generating layer and a charge transport layer have suitable interfacial properties for effective charge transfer. The composition that forms a charge transport layer on an electroconductive support contains a first charge transport compound that is soluble in an acetate solvent, a second charge transport compound that is insoluble in an acetate solvent, a binder resin, and an organic solvent. The method of manufacturing the photoreceptor includes: coating a surface of an electroconductive support with the charge transport layer forming composition and drying the surface to form a charge transport layer; and coating a surface of the charge transport layer with a charge generating layer forming composition and drying the surface to form a charge generating layer.

摘要： A double-layered positively-charged organic photoreceptor has a charge transport layer with effective adhesion to an electroconductive support and effective resistance against dissolving when in contact with a hydrocarbon-based solvent of a wet developer. Therefore, the double-layered positively-charged organic photoreceptor requires neither anodizing on the electroconductive support nor an additional adhesive layer, and is compatible with wet developing methods. The double-layered positively-charged organic photoreceptor includes: an electroconductive support; a charge transport layer formed on a surface of the electroconductive support and including a charge transport material for transporting holes, a polycarbonate-based first binder resin, and a second binder resin of a polyester copolymer with a biphenylfluorene group; and a charge generating layer formed on the surface of the charge transport layer.
