Abstract
Disclosed is a semiconductive rubber roller used as a developing roller in a photocopying printer machine exhibiting excellent performance and outstanding durability. The rubber roller is an integral body comprising (a) a shaft of a metallic material, (b) a base rubber layer on and around the shaft formed from a semiconductive silicone rubber having a specified volume resistivity and (c) a cladding layer having a specified thickness on and around the base rubber layer formed from a synthetic resin composition compounded with a specified amount of particles of a dielectric material, such as silica, having a dielectric constant of 2.0 to 8.0 and a specified average particle diameter.
