Abstract
An electrophotographic photoreceptor, an electrophotographic photoreceptor cartridge, and an image forming apparatus, which are excellent in electrical characteristics such as a responsivity and at the same time, excellent in the crack resistance, are provided. Two kinds of charge transport substances each having a specific structure and a polyester resin having a specific structure are combined, whereby the crack resistance can be improved.
