RUBBER COMPOSITION FOR SEMICONDUCTOR ROLLER AND SEMICONDUCTOR ROLLER

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for a semiconductor roller having little environmental dependency and the semiconductive roller using it in the roller using ionic conductive rubber for a semiconductive layer. SOLUTION: This rubber composition for the semiconductive roller is added with carbon black made of furnace black of the pts.wt. 2/3 times the average grain size (μm) or above to ionic conductive base rubber of 100 pts.wt. An elastic layer is formed with the rubber composition for the semiconductive roller on the semiconductive roller.
