Electrically conductive roll whose base layer is formed of ion-conductive elastic material

摘要

An electrically conductive roll is disclosed, which includes: a center shaft (10); a base layer (12) formed on an outer circumferential surface of the center shaft and including an elastic material as a major component and an ion-conductive material, the base layer having a volume resistivity of 10<6>-10<9> OMEGA cm; an electrode layer (14) formed on an outer surface of the base layer and including a synthetic resin material as a major component and an electron-conductive material, the electrode layer having a volume resistivity of not more than 10<3> OMEGA cm; a resistance adjusting layer (16) formed on an outer surface of the electrode layer; and a protective layer (18) formed on an outer surface of the resistance adjusting layer.
