PROBLEM TO BE SOLVED: To provide an amine compound as a charge transporting substance which can form a printed image excellent in clarity without image defects (for example, a dot defect in the halftone and formation of fogging) even when a number of prints are made with the use of an image-forming devices mounting short wavelength laser beams, an electrophotographic photoreceptor, and an image-forming device. SOLUTION: The amine compound is represented by formula (1) (wherein Ar<SP>1</SP>, Ar<SP>2</SP>, Ar<SP>4</SP>, and Ar<SP>5</SP>are each an aryl group which may have a substituent; Ar<SP>3</SP>and Ar<SP>6</SP>are each an arylene group which may have a substituent; X<SP>1</SP>and X<SP>2</SP>are each an alkyl group which may have a substituent, an aryl group or an alkoxy group and may be linked with each other to have a cyclic structure containing a heterocycle; and furthermore any of Ar<SP>1</SP>to Ar<SP>6</SP>, X<SP>1</SP>, and X<SP>2</SP>contains one or more substituents comprising a biphenyl group, a naphthyl group, and a derivative thereof).
