[Object] To provide an electrically conductive polymer member, which can be stably used with a reduced variation in electrical resistance even when its use environment is changed or continuous energization is conducted, and furthermore, a transfer roller and an image forming device, which can stably produce good images by using the electrically conductive polymer member. [Solving Means] An electrically conductive polymer member is formed from an electrically conductive polymer material prepared by adding a quaternary ammonium salt and a lithium imide to a base polymer. When the amounts of compounding of the quaternary ammonium salt and the lithium imide are assumed to be x parts by weight and y parts by weight, respectively, it is preferable that x and y satisfy the following formula: 0.009≦(y/x)≦0.019. A transfer roller and an image forming device are provided with their respective electrically conductive polymer members.
