PROBLEM TO BE SOLVED: To provide a stilbene derivative suitable as a charge transfer agent for electrophotographic photoreceptor, etc., a method for producing the derivative and an electrophotographic photoreceptor having excellent sensitivity characteristics. SOLUTION: The invention provides a stilbene derivative having three triphenylamine structures containing ethenyl group, a method for the production of the derivative and an electrophotographic photoreceptor containing the stilbene derivative. The stilbene derivative is expressed by general formula (1) (A is a trivalent organic group containing a substituted or unsubstituted aromatic ring; multiple R<SP>1</SP>-R<SP>6</SP>groups are each independently hydrogen atom, a halogen atom, a 1-20C substituted or unsubstituted alkyl, a 1-20C substituted or unsubstituted halogenated alkyl or the like; and multiple Ar<SP>1</SP>and Ar<SP>2</SP>groups are each a 6-30C substituted or unsubstituted aryl group).
