Abstract
An object of the present invention is to provide a conductive rubber member which exhibits small environmental dependency and stable electrical resistance. The conductive rubber member is formed of a conductive elastic layer which has been imparted with conductivity by means of a conductivity-imparting agent. The conductive elastic layer has, at a surface portion thereof, a surface-treated layer which has been formed through impregnating the surface with a surface-treatment liquid containing an isocyanate component and an ion-conducting polymer.
