PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that exhibits sufficient abrasion resistance necessary for a long-term use, suppresses the occurrence of filming, poor cleaning, and abnormal noise, has an excellent adhesive property to a substrate and an undercoat layer, shows quick response and a sufficiently low potential for an exposure part on electric characteristics, and has excellent gas resistance and an image memory property; an electrophotographic photoreceptor cartridge; and an image forming apparatus.SOLUTION: A photosensitive layer using a specific polyester resin as a binder resin is made to contain a charge transport material having a specific structure so as to exhibit good performance on mechanical characteristics and show a sufficiently low residual potential during exposure. |
