<p>The present invention relates to a stilbeneamine derivative represented by a formula (1) : <CHEM> wherein Ar<1> and Ar<2> each denote an aryl group; Ar<3> denotes an arylene group; Ar<4> denotes an arylene group or divalent heterocyclic group; provided that when a thiophene ring in the formula is 2-thiophenyl, 'n' is 1 and when the thiophene ring is 3-thiophenyl, 'n' is 0 or 1, and also relates to an electrophotosensitive material comprising a photosensitive layer containing this derivative. The derivative is excellent in electric charge transferring capability, compatibility with a binder resin and stability, thus offering the electrophotosensitive material superior to the prior-art products in sensitivity and repeatability.</p> |
