PROBLEM TO BE SOLVED: To provide an elastic member of a semiconductive polymer, having characteristics that are superior, in both the voltage dependence and environmental dependence of the electrical resistance. SOLUTION: An elastic member of a semiconductive polymer, comprising a conductive composition containing a conductive polymer and a binder polymer, is provided, wherein the elastic member satisfies both characteristics of (A) dispersion of 1.5 digits or smaller between the electrical resistance at an applied voltage of 1V and the electrical resistance at an applied voltage of 133V under the environment of 25°C×50%RH, and (B) a dispersion of one digit or smaller, between the electrical resistance at an applied voltage of 10V under the environment of 15°C×10%RH, and the electrical resistance at an applied voltage of 10V under the environment of 35°C×85%RH.
