US 7,563,548 B2 · Amine compound, manufacturing method thereof, electrophotographic photoreceptor using amine compound and image forming apparatus having the same

Abstract

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 Ar1, Ar2 and Ar3 each represents an optionally-substituted aryl group, or an optionally-substituted monovalent heterocyclic ring residue. Ar4 represents an optionally-substituted arylene group, or an optionally-substituted bivalent heterocyclic ring residue. R1 represents an optionally-substituted alkyl group, an optionally-substituted aryl group, an optionally-substituted monovalent heterocyclic ring residue, or an optionally-substituted aralkyl group. R2 and R3 each 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 R2 may be identical with or different from each other, and two R3 may be identical with or different from each other).
