Abstract
Official abstract text for this publication.
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 polycarbonate resin having a specific structure are combined, whereby the electrical characteristics such as responsivity and the crack resistance can be improved at the same time.
First claim
