Abstract

An electrophotographic photosensitive member includes a photosensitive layer containing a naphthalenediimide derivative represented by the following formula (1) or (2). In the formula (1) or (2), R 1 represents an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 12 carbon atoms and optionally having an alkyl group having 1 to 10 carbon atoms, an aralkyl group having 7 to 12 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, or an alkoxy group having 1 to 6 carbon atoms.

Description

Technical field [0001] The invention relates to an electrophotographic photoreceptor. Background technique [0002] As an electrophotographic photoreceptor provided in an image forming apparatus or the like, an organic photoreceptor containing a binder resin, a charge generating agent, a hole transporting agent as a charge transporting agent, an electron transporting agent, and the like is known. Compared with inorganic photoreceptors using inorganic materials such as amorphous silicon, such organic photoreceptors are easier to manufacture, and because the selection of photoreceptor materials can be diversified, it has the advantage of high degree of freedom in structural design. [0003] Furthermore, in order for an image forming apparatus using an organic photoreceptor to form a high-quality image, the material contained in the organic photoreceptor in the electrophotographic photoreceptor is required to have sufficient sensitivity characteristics. [0004] Here, especially regard...
