Charging roller including a conductive cover layer being formed of a seamless tube, process cartridge and electrophotographic image forming apparatus including such a charging roller
摘要：
In a charging roller having a support member and a conductive cover layer, the conductive cover layer is formed of a seamless tube. The seamless tube contains at least (A) a thermoplastic styrene elastomer, (B) a polystyrene resin and (C) a carbon black, and the proportion of the component (A) to the component (B) is (A)/(B)=60/40 to 20/80 in weight ratio. A process cartridge and an electrophotographic apparatus have such a charging roller.
摘要（中）：

在具有支撑构件和导电覆盖层的充电辊中，导电覆盖层由无缝管形成。 该无缝管至少包含（A）热塑性苯乙烯弹性体，（B）聚苯乙烯树脂和（C）炭黑，组分（A）与组分（B）的比例为（A）/（B ）= 60/40〜20/80重量比。 处理盒和电子照相设备具有这种充电辊。
