Electrically conductive roller and image-forming device

摘要

This invention provides an electrically conductive roller capable of forming an image without fogging even in a low humidity environment and an image-forming device. Specifically, the invention relates to an electrically conductive roller has an elastic layer formed on an outer circumferential surface of a shaft and a urethane coat layer formed on an outer circumferential surface of the elastic layer, wherein the urethane coat layer includes a urethane resin, and at least one ionic liquid selected from the group consisting of pyridinium ionic liquids and amine ionic liquids, in an amount from 1 to 20 parts by mass to 100 parts by mass of the urethane resin; and an image-forming device equipped with the electrically conductive roller.
