DEVELOPMENT ROLLER FOR ELECTROPHOTOGRAPHY DEVICE

摘要

The disclosed development roller for a electrophotography device does not cause bleeding or blooming, has low hardness, low permanent set-in fatigue and low resistance, is capable of obtaining uniform volume resistivity, and has excellent charge decay properties. The disclosed development roller has a shaft (12) and an elastic rubber layer (14) formed around the outside of the shaft (12). The elastic rubber layer (14) is formed from a cross-linked product of a composition comprising a liquid or millable silicone rubber, a cross-linking agent, an electron conductive agent, and an ionic liquid, wherein said composition contains 0.1-5.1 mass% ionic liquid relative to the total 100 mass% of the liquid or millable silicone rubber and the cross-linking agent.
