PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that quantitatively grasps crack resistance against a contact member to have excellent responsiveness and crack resistance, an electrophotographic photoreceptor cartridge, and an image forming apparatus.SOLUTION: In an electrophotographic photoreceptor having at least photosensitive layer on a conductive support, two types of charge transport materials having a specific structure and a polyester resin can be combined to be contained in the single photosensitive layer to improve crack resistance. |
