Abstract
An elastic member of a semiconductive polymer comprising a conductive composition containing a conductive polymer and binder polymer, wherein the elastic member satisfies both characteristics of (A) a variation of 1.5 digit or less between the electrical resistance at an applied voltage of 1V and the electrical resistance at an applied voltage of 133V under an environment of 25° C. and 50% RH, and (B) a variation of one digit or less between the electrical resistance at an applied voltage of 10V under an environment of 15° C. and 10% RH and the electrical resistance at an applied voltage of 10V under an environment of 35° C. and 85% RH.
