Abstract:
An electrophotographic photosensitive member includes a conductive substrate and a photosensitive layer. The photosensitive layer is a single-layer photosensitive layer. The photosensitive layer contains a charge generating material, a hole transport material, an electron transport material, a binder resin, and an additive. The additive contains a carboxylic acid anhydride. A reduction potential of the carboxylic acid anhydride is at least −1.40 V versus a reference electrode (Ag/Ag + ). The carboxylic acid anhydride is contained in an amount of at least 0.02 parts by mass and no greater than 10.00 parts by mass relative to 100 parts by mass of the binder resin.

Claim (Index 7):
The electrophotographic photosensitive member according to  claim 1 , wherein\n the electrophotographic photosensitive member is included as an image bearing member in an image forming apparatus, the image forming apparatus includes: the image bearing member; a charger configured to charge a surface of the image bearing member; a light exposure section configured to expose the charged surface of the image bearing member to light to form an electrostatic latent image on the surface of the image bearing member; a development section configured to develop the electrostatic latent image into a toner image; and a transfer section configured to transfer the toner image from the image bearing member to a recording medium, the charger has a positive charging polarity, and a surface potential of an exposed region of the image bearing member is at least \u221230 V, the exposed region being a region exposed to light by the light exposure section, the surface potential being measured after transfer of the toner image from the image bearing member to the recording medium by the transfer section and before charging by the charger for a next rotation of the image bearing member.
