CHARGING MEMBER, ELECTROPHOTOGRAPHIC DEVICE AND PROCESS CARTRIDGE |
摘要 |
A charging member is provided which has a low electrical resistance, has less non-uniformity or environmental dependence of the electrical resistance, may less undergo electrification deterioration even when used for a long period of time, and is free of any occurrence of faulty images such as horizontal lines attributable to charging. The charging member is formed of a support with a good electrical conductivity and an elastic layer consisting of at least one layer on the support, and the elastic layer is formed of a semiconductive vulcanized rubber in which carbon black has been dispersed as conductive particles in a binder polymer containing a polymer having a butadiene skeleton, having been modified at a molecular terminal thereof with a specific atomic group. |
