Abstract
A method of manufacturing an electrophotographic photosensitive member includes the steps of: cleaning a substrate of the electrophotographic photosensitive member by cleaning step using a vessel and machining the substrate. The cleaning step includes a first overflowing step and a second overflowing step. In the first overflowing step, the liquid is allowed to be overflowed from a vessel while the substrate of the electrophotographic photosensitive member is immersed in the liquid contained in the vessel. In the second overflowing step, the liquid is allowed to overflow from a vessel while the substrate of the electrophotographic photosensitive member is pulled up in the liquid contained in the vessel. A flow rate Q of the overflowing liquid of the second overflowing step is higher than a flow rate Q of the overflowing liquid of the first overflowing step. The machining step forms a film of a photosensitive substance on the substrate.
