An electrophotographic photosensitive member is disclosed which is excellent in cleaning performance, has improved durability, and suppresses image defects in various environments. The electrophotographic photosensitive member has a support and a photosensitive layer provided on the support. Depressed portions independent of one another are formed on the surface of the electrophotographic photosensitive member so that the number of the depressed portions per 100 .mu.m square is 76 or more and 1,000 or less. The openings of the depressed portions have an average major axis diameter of more than 3.0 .mu.m and 14.0 .mu.m or less.
