An amine compound represented by the general formula (1), which is incorporated as a charge-transporting substance to a charge-transporting layer of an electrophotographic photoreceptor: (in which Ar, Arand Areach represents an optionally-substituted aryl group, or an optionally-substituted monovalent heterocyclic ring residue. Arrepresents an optionally-substituted arylene group, or an optionally-substituted bivalent heterocyclic ring residue. Rrepresents an optionally-substituted alkyl group, an optionally-substituted aryl group, an optionally-substituted monovalent heterocyclic ring residue, or an optionally-substituted aralkyl group. Rand Reach represents a hydrogen atom, an optionally-substituted alkyl group, an optionally-substituted aryl group, an optionally-substituted monovalent heterocyclic ring residue, or an optionally-substituted aralkyl group. n represents an integer of 1 or 2. When n represents 2, two Rmay be identical with or different from each other, and two Rmay be identical with or different from each other).
