Abstract:
A method of manufacturing an electrophotographic photosensitive member, said method comprising the steps of:(i) cleaning a substrate of the electrophotographic photosensitive member by a cleaning method using a liquid, which is contained in a vessel, wherein said cleaning step includes: a first overflowing step, wherein the liquid is allowed to be overflowed from the vessel while the substrate of the electrophotographic photosensitive member is immersed in the liquid contained in the vessel; and a second overflowing step, wherein the liquid is allowed to overflow from the vessel while the substrate of the electrophotographic photosensitive member is pulled up in the liquid contained in the vessel, wherein a flow rate Q2 of the overflowing liquid of said second overflowing step is higher than a flow rate Q1 of the overflowing liquid of said first overflowing step, and (ii) machining the cleaned substrate of the electrophotographic photosensitive member, wherein said machining step forms a film of a photosensitive substance on the substrate.
