Abstract:
An electrophotographic photosensitive member, wherein fluctuation in potential is suppressed, and the occurrence of black spots is suppressed even if the electrophotographic photosensitive member is repeatedly used for a long period of time is provided. A process cartridge that is equipped with the electrophotographic photosensitive member and an electrophotographic apparatus that is equipped with the process cartridge are provided. An electrophotographic photosensitive member, wherein an undercoat layer of the electrophotographic photosensitive member contains an aluminum oxide particle that is surface-treated in a specific amount using a specific compound.

Claim (Index 10):
An electrophotographic apparatus comprising an electrophotographic photosensitive member, a charging unit, an exposing unit, a developing unit and a transfer unit, wherein\n the electrophotographic photosensitive member comprises a support, an undercoat layer and a photosensitive layer in this order, wherein the undercoat layer contains a binder resin, and an aluminum oxide particle which is surface-treated with a compound represented by the following formula (1), wherein R 1  to R 3  each independently represent an alkoxy group or an alkyl group, provided that at least two of R 1  to R 3  are alkoxy groups, and R 4  is an alkyl group having n carbon atoms (6\u2264n\u226418), and wherein when an amount of aluminum atoms in the surface-treated aluminum oxide particle is represented by M Al  and an amount of silicon atoms derived from the compound represented by the formula (1) is represented by M Si , a product of an amount X used for surface treatment defined by X=(M Si /M Al )\u00d7100 (% by mass) and a number n of carbon atoms in R 4  (X\u00d7n) is 10 or more and 330 or less.
