ABSTRACT:
Disclosed is an electric charging member for charging a body to be charged by bringing the electric charging member in contact with the body to be charged and applying a voltage between the electric charging member and the body to be charged, including: an elastic layer; and a covering layer formed on the outer side of the elastic member directly or through another layer; wherein the covering layer is formed of a coating having a storage modulus (G') in a range of 1.times.10.sup.7 dyn/cm.sup.2 or less, and also having tan .delta., expressed by a ratio (G"/G') of a loss modulus (G") to the storage modulus (G'), in a range of 0.01 to 0.4. The electric charging member is allowed to suppress occurrence of compressive deformation and to reduce noise due to electrification.
