摘要： Concerned with a charging member in the conductive surface layer of which the conductive particles are so kept from agglomerating as to make charging performance not easily change even where the surface layer expands and contracts repeatedly in various environments. The charging member is a charging member having a conductive substrate and formed on the substrate a conductive elastic layer and a conductive surface layer. The elastic layer contains a polymer having a unit coming from ethylene oxide, and the surface layer contains a binder resin and graphitized particles. The binder resin contains a resin having in the molecule a urethane linkage or a siloxane linkage, or a urethane linkage and a siloxane linkage, and the graphitized particles have a graphite (002) plane lattice spacing of from 0.3362 nm or more to 0.3449 nm or less.

摘要： When a polymer blend of an NBR and an alkylene oxide-polymerized polymer is used as the electro-conductive elastic layer of an electro-conductive member for electrophotography, a change in shape of the electro-conductive member occurs owing to its expansion due to water absorption, thereby causing image unevenness in some cases. In addition, when the ratio at which the alkylene oxide-polymerized polymer is blended is reduced for suppressing the shape change due to water absorption, image unevenness resulting from the insufficiency of electro-conductivity occurs in some cases. When an electro-conductive member for electrophotography having an electro-conductive elastic layer containing an NBR to which a specific alkylene oxide oligomer is graft-bonded is used, high ionic electro-conductivity is obtained and a change in its shape due to water absorption is reduced.
摘要翻译：当使用NBR和烯化氧聚合的聚合物的聚合物共混物作为用于电子照相的导电部件的导电弹性层时，导电部件的形状由于水的膨胀而发生变化吸收，从而在某些情况下引起图像不均匀。此外，为了抑制由于吸水而引起的形状变化，当混合烯化氧聚合的聚合物的比例降低时，在某些情况下会发生由电导率不足导致的图像不均匀。使用具有含有特定环氧烷低聚物的NBR的导电性弹性层的电子照相用导电性构件时，可以获得高离子导电性，并且由于吸水而导致的形状变化为减少
