Abstract
A photoconductive layer having superior characteristics is made by steps of suspending uniformly photoconductive particles in a viscous solution by stirring, pouring the stirred mixture of the photoconductive particles, binder and solvent on a substrate which is put horizontally at a bottom of a container, precipitating the photoconductive particles on the surface of the substrate so as to form a wet photoconductive layer, removing the clear solution on the wet photoconductive layer, drying the wet photoconductive layer and baking the dried photoconductive layer.
