摘要：<p>PROBLEM TO BE SOLVED: To provide a semiconductive rubber composition which has uniform electric characteristics, a little dependency on voltage, and little effect on envi ronmental changes and is also stable with the elapse of time and is capable of producing an electrified member in which soiling of the members to be elec trized, such as a photosensitive member is suppressed. SOLUTION: This semiconductive rubber composition forms a sea-island structure which includes a polymer continuous phase 11 composed of an ionic conductive rubber material made up mainly of a material rubber A having a volume resistivity of 1×1012Ω.cm or less and also includes a polymer particulate phase 12 composed of an electronic conductive rubber material compounded of conductive particles.</p>
