Electrophotographic photosensitive member

An electrophotographic photosensitive member comprising a conductive substrate and a photosensitive layer, wherein

• the photosensitive layer is a single layer,
• the photosensitive layer contains at least a charge generating material and a compound represented by a general formula (1) shown below:
• where in the general formula (1),
• R1 represents an aryl group having a carbon number of at least 6 and no greater than 22 and optionally having an alkyl group having a carbon number of at least 1 and no greater than 10, an alkyl group having a carbon number of at least 3 and no greater than 20, an aralkyl group having a carbon number of at least 7 and no greater than 20, a cycloalkyl group having a carbon number of at least 3 and no greater than 20, or an alkoxy group having a carbon number of at least 1 and no greater than 6, and
• chemical groups R2 each represent a halogen atom.
