PROBLEM TO BE SOLVED: To provide a semiconductive silicone rubber roll having smooth surface, capable of being reduced in hardness, and excellent in the stability of hardness and resistance value. SOLUTION: This semiconductive silicone rubber roll is a 2-layered silicone rubber roll constituted so that an insulating silicone rubber foamed body layer 3 is formed on the outer peripheral surface of a conductive core 2 and further, a conductive silicone rubber layer 4 is formed on the outer peripheral surface of the foamed body layer 3, and a pair of ring-like semiconductive silicone rubber plates 5 are integrally formed between the inner peripheries of the projected parts of the conductive silicone rubber layer 4 formed in contact with both end faces of the insulating silicone rubber foamed body layer 3 and project both end faces from the foamed body layer 3 and the outer periphery of the conductive core 2. |
