PROBLEM TO BE SOLVED: To provide a stilbene derivative having excellent compatibility with a binder resin owing to the presence of three diphenylenamine structures at prescribed parts in the molecule of a stilbene derivative and exhibiting a prescribed sensitivity from the initial stage for a long period, a method for the production of the stilbene derivative and an electrophotographic receptor containing the stilbene derivative. SOLUTION: The stilbene derivative has three diphenylenamine structures and is expressed by general formula (1) (A is a trivalent organic group containing a substituted or unsubstituted aromatic ring; and R<SP>1</SP>to R<SP>7</SP>, B<SP>1</SP>and B<SP>2</SP>are each independently hydrogen atom, a halogen atom, a 1-20C substituted or unsubstituted alkyl or the like wherein the B<SP>1</SP>and B<SP>2</SP>groups may be bonded or condensed to form a substituted or unsubstituted carbon ring structure). The invention further relates to a method for the production of the stilbene derivative and an electrophotographic receptor containing the stilbene derivative. COPYRIGHT: (C)2005,JPO&NCIPI
