摘要：
An electro-conductive roll is provided that makes contact with a body to be charged in a state in which a voltage is applied thereto, and charges the body to be charged, a surface of the electro-conductive roll satisfying the following conditions (a) and (b): (a) the surface of the electro-conductive roll has a 10-point average roughness of 5 μm or less; and (b) the surface of the electro-conductive roll has a dynamic ultra-microhardness in the range of 0.04 to 0.5.
