[PROBLEMS] To form a conductive rubber layer containing polar rubber as an essential component, free from contamination of a photoreceptor due to exudation of a plasticizer or a softener, having low hardness and excellent compression set, kneading and extrusion processability In addition, an excellent conductive rubber composition is provided. When the total amount of polar rubber and nonpolar rubber is 100 parts by mass, the polar rubber is 20 to 100 parts by mass, and further includes a paraffinic oil having polarity. Rubber composition.
