ABSTRACT:
An electrophotographic photosensitive member is provided in which both a potential variation over a long time period and a potential variation within a short time period are suppressed. A method of producing the electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member are also provided. In the electrophotographic photosensitive member, an intermediate layer is a layer formed by coating and drying a coating liquid for an intermediate layer, containing an acidic titania sol and an organic resin, and the acidic titania sol is an acidic sol containing anatase-type titanium oxide crystal particles having an average primary particle diameter of 3 nm or more and 9 nm or less.
