ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS FOR PRODUCING ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

An electrophotographic photosensitive member is provided in which both a fluctuation in potential over a long time period and a fluctuation in potential 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 applying and drying an application 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.
