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 present invention relates to an electrophotographic photoreceptor. Background technique [0002] As an electrophotographic photoreceptor included in an image forming apparatus or the like, an organic photoreceptor including 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 an organic photoreceptor is easy to manufacture, and has the advantage of a high degree of freedom in structural design because the choice of photoreceptor materials can be diversified. [0003] Furthermore, in order for an image forming apparatus using an organic photoreceptor to be able to form a high-quality image, materials contained in the organic photoreceptor in the electrophotographic photoreceptor are required to have sufficient sensitivity characteristics. [0004] Here...
