Electrophotographic photoreceptor, process cartridge, image forming apparatus, and imide compound

Abstract

An electrophotographic photoreceptor includes a conductive substrate; a photosensitive layer provided on the conductive substrate; and an undercoating layer that is provided between the conductive substrate and the photosensitive layer and includes a charge transport material containing at least one of imide compounds represented by Formula (1) or (2): (in Formulas (1) and (2), R10, R11, R20 or R21 independently represents a group represented by Formula (3) or (4) where X represents a monovalent organic group having at least one of an alkyl group, an alkylene group, an ether group, an ester group, and a keto group, a halogen atom, a nitro group, an aralkyl group, or an aryl group, Y represents a sulfur atom or an oxygen atom, n represents an integer of 0 to 2, and when n represents 2, two X's may be the same or different), and an imide compound is represented by Formula (1A) where Ar represents an aromatic group having 6 to 18 carbon atoms except for a tetravalent perylene group, X1 and X2 each independently represent a nitrogen atom or a substituted or unsubstituted carbon atom, Y1 and Y2 each independently represent an oxygen atom, a sulfur atom, a selenium atom, or NH, and R1 and R2 each independently represent a hydrogen atom or a monovalent organic group:
