Abstract
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.
