Abstract
Disclosed is a production process of an organic photoreceptor which can suppress occurrence of uneven density and image defects. The production process of an organic photoreceptor, the organic photoreceptor including an intermediate layer and an organic photosensitive layer on the intermediate layer, includes: applying a coating liquid for forming the intermediate layer to a conductive support to form a coating film, the coating liquid being obtained by dissolving a binder resin in a solvent and dispersing first and second metal oxide fine particles therein; and drying the coating film. The Pe number of the first metal oxide fine particles is two or more times larger than that of the second metal oxide fine particles.number=(6πμ)/  Equation (1):
