PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that suppresses optical fatigue even when a specific fluorene compound and diamine compound are used in combination, in particular, a variation in potential immediately after exposure of external light, and suppresses an increase in residual potential even if repeatedly used after that; an electrophotographic cartridge; and an image forming apparatus.SOLUTION: An electrophotographic photoreceptor is used in a negative charging system including at least a charge generating layer and a charge transport layer on a conductive support. The electrophotographic photoreceptor uses a compound having a specific structure in combination with a fluorene compound and a diamine compound responsible for charge transport. |
