Electrophotographic photosensitive member, process cartridge and electrophotographic apparatus

An electrophotographic photosensitive member comprising a support and a photosensitive layer formed on the support and containing a silicon-containing compound or a fluorine-containing compound in a surface layer in an amount of 0.6% by mass or more relative to a total solid matter of the surface layer, the electrophotographic photosensitive member being used in contact with a cleaning blade on the surface thereof, wherein:

• the electrophotographic photosensitive member has depressed portions which are independent from one another, in a number of from 50 or more to 70,000 or less per unit area (100 μm×100 μm), at least over the entire region of a surface portion of the electrophotographic photosensitive member which is in contact with the cleaning blade, and, the depressed portions each have a ratio of a depth (Rdv) that shows a distance between the deepest part of each depressed portion and the opening surface thereof to a major axis diameter (Rpc) of each depressed portion, Rdv/Rpc, of from more than 0.3 to 7.0 or less, and a depth (Rdv) of from 0.1 μm or more to 10.0 μm or less;
• and
• the total present ratio of a fluorine element and a silicon element relative to constitutional elements in an outermost surface of the surface layer of the electrophotographic photosensitive member obtained by x-ray photoelectron spectroscopy (ESCA) is 1.0% by mass or more;
• and a ratio (A/B) is larger than 0.0 and smaller than 0.5, where A (% by mass) is defined as a total content of a fluorine element and a silicon element present at a portion 0.2 μm inward from the outermost surface of the surface layer of the electrophotographic photosensitive member and B (% by mass) is defined as a total content of a fluorine element and a silicon element present in the outermost surface, with the contents of the fluorine element and silicon element obtained with x-ray photoelectron spectroscopy (ESCA).
