PROBLEM TO BE SOLVED: To provide an amino compound as a charge transporting substance which forms 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 using an image forming device mounting short wavelength laser beams, an electrophotographic photoreceptor, and an image forming device. SOLUTION: This electrophotographic photoreceptor has a photosensitive layer containing at least a charge generating substance and the charge transporting substance on a conductive support body. The electrophotographic photoreceptor contains, as the charge transporting substance, compound 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 independently have a substituent, and Ar<SP>3</SP>and Ar<SP>6</SP>are each an arylene group which may independently have a substituent. X<SP>1</SP>and X<SP>2</SP>are each an alkyl group, an aryl group or an alkoxy group, which may independently have a substituent, and may be linked with each other to have a cyclic structure containing a heterocycle. Furthermore, one of X<SP>1</SP>and X<SP>2</SP>contains one or more substituents having a skeleton of one of benzotriazol, benzophenone, benzoate, triazine and cyano diphenyl acrylate.
