PROBLEM TO BE SOLVED: To obtain a new triarylamine compound having a dialkylamino group, useful as a photoconductive material for a photoreceptor for an electrophotography, having high durability against a long-term repeated use, suppressing the deterioration of an image caused by the reduction of image density and the formation of an indistinct image, and stably providing a high resolution image. SOLUTION: This triarylamine compound is represented by formula (1) (wherein, R<SP>1</SP>is the same or different and a 1-4C alkyl group; R<SP>1</SP>and R<SP>2</SP>may form a heterocyclic group containing nitrogen atom by bonding to each other; R<SP>2</SP>is a 1-4C alkyl group or a substituted or nonsubstituted aromatic group; and Ar is a substituted or nonsubstituted aromatic group), and has at least one dialkylamino group.
