Semiconductive roller

A semiconductive roller comprising a roller body made of a crosslinking product of a rubber composition, the rubber composition comprising:

• a rubber component consisting of a styrene butadiene rubber, an epichlorohydrin rubber, and a chloroprene rubber;
• and
• a crosslinking component for crosslinking the rubber component;
• wherein the styrene butadiene rubber is present in the rubber component in a proportion of not less than 50 parts by mass and not greater than 90 parts by mass based on 100 parts by mass of the rubber component,
• wherein the epichlorohydrin rubber is present in a rubber component in a proportion of not less than 5 parts by mass and not greater than 40 parts by mass based on 100 parts by mass of the rubber component,
• wherein the chloroprene rubber is present in the rubber component in a proportion of not greater than 10 parts by mass based on 100 parts by mass of the rubber component,
• wherein the crosslinking component consists of a sulfur crosslinking agent and a thiazole accelerating agent,
• wherein the thiazole accelerating agent is present in the crosslinking component in a proportion of not less than 0.75 parts by mass and not greater than 3 parts by mass based on 100 parts by mass of the rubber component.
