摘要：
An electrophotographic photosensitive member is provided in which both a long-term potential variation and a short-term potential variation are suppressed, and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member are also provided. The intermediate layer of the electrophotographic photosensitive member includes an organic resin and rutile-type titanium oxide crystal particles which contain tin and have an average primary particle diameter of 3 nm or more and 9 nm or less.
