Abstract:
An electrographic photoreceptor (1) is provided with an electroconductive base (2) and a photosensitive layer (3). The photosensitive layer (3) is a single-layer photosensitive layer. The photosensitive layer (3) includes a charge-generating agent, a hole transport agent, an electron transport agent, a binder resin, and an acid anhydride. The acid anhydride is represented by formula (1), formula (2), or formula (3). In formulae (1) and (2), Ra, Rb, Rc, and Rd each represent, independently: a C1-6 alkyl group that optionally having a hydrogen atom, a halogen atom, and a first substituent group; a C1-6 alkoxy group that optionally has a second substituent group; or a C6-14 aryl group that optionally has a third substituent group.
