Abstract

The invention provides an electrophotographic photoreceptor and an image forming device. The electrophotographic photoreceptor contains a terphenylquinone derivative represented by the following general formula (1). [Chemical formula 1] In the above general formula (1), R1 to R5 are the same or different, represent a hydrogen atom, an alkyl group with a carbon number of 1 to 12, and have or do not have a carbon number of 1 or more and The alkyl group having 12 or less is an aryl group having 6 to 12 carbon atoms, an aralkyl group having 6 to 12 carbon atoms, a cycloalkyl group having 3 or more and 10 or less carbon atoms, or an alkoxy group having 2 to 6 carbon atoms.

Description

technical field [0001] The present invention relates to an electrophotographic photoreceptor containing a specific terphenoquinone derivative, and an image forming apparatus including the electrophotographic photoreceptor. Background technique [0002] As electrophotographic photoreceptors provided in image forming apparatuses, organic photoreceptors and inorganic photoreceptors are known. The organic photoreceptor contains a binder resin, a charge generator, a hole transport agent, and an electron transport agent. The inorganic photoreceptor contains an inorganic material such as amorphous silicon. Compared with inorganic photoreceptors, organic photoreceptors are easy to manufacture and there are many options for photoreceptor materials, so the degree of freedom in structural design is high. [0003] In order to form an image with high image quality by an image forming apparatus using an organic photoreceptor, materials contained in the organic photoreceptor are required...
