PROBLEM TO BE SOLVED: To obtain a stilbene derivative that is hardly crystallized, has excellent compatibility with a binder resin and predetermined sensitivity not only at the early stage but also for many hours by having a triphenylamine structure containing a diphenylethenyl group in the molecule of a stilbene derivative, to provide a method for producing the same and to obtain an electrophotographic photoreceptor containing the stilbene derivative. SOLUTION: The stilbene derivative has a triphenylamine structure containing a diphenylethenyl group. The stilbene derivative is represented by formula (1) (R<SP>1</SP>, R<SP>2</SP>, R<SP>4</SP>-R<SP>10</SP>and R<SP>12</SP>-R<SP>16</SP>are each independently a 1-20C substituted or nonsubstituted alkyl group or the like; R<SP>3</SP>and R<SP>11</SP>are each a 1-20C substituted or nonsubstituted alkyl group or a 14-30C substituted or nonsubstituted diphenylethenyl group or the like; a repeating number A is an integer of 2-6). The electrophotographic photoreceptor comprises the stilbene derivative. COPYRIGHT: (C)2005,JPO&NCIPI
