Abstract:
A development roll for electrophotographic equipment includes a shaft body and a rubber elastic layer disposed on the outer circumference of the shaft body. The rubber elastic layer is composed of a crosslinked body of a composition containing a liquid or millable silicone rubber, a crosslinking agent, an electronically conductive agent, and an ionic liquid. The composition contains the ionic liquid in the amount in the range of 0.1 to 5.1 parts by mass relative to 100 parts by mass of the total amount of the liquid or millable silicone rubber and the crosslinking agent.
