ELECTRIFICATING MEMBER AND ELECTROPHOTOGRAPHIC DEVICE |
摘要 |
<p>To provide a charging member that can have a uniform electrical resistance, can not easily change in electrical resistance even by any long-term continuous electrification and, as a result thereof, may cause less change in its charging performance with time. A charging member having a conductive support and an elastic-material layer; the elastic-material layer comprising a vulcanized rubber; the vulcanized rubber being a vulcanized product of a composition which comprises i) a binder polymer comprising a polymer having a butadiene skeleton and ii) carbon black as electrically conductive particles; and the polymer having a butadiene skeleton has a molecular terminal modified with an atomic group having a specific structure.</p> |
