Abstract
A conductive member for OA equipment (electrophotographic apparatus or electrostatic recording apparatus) which is obtainable from a composition comprising a non-ether-based polyurethane, carbon black and bis(trifluoromethanesulfonyl)imidolithium. The conductive member shows very stable conductivity in the volume resistivity range of 10to 10Ω·cm, the conductivity of which is less dependent on the voltage applied and varies only slightly during continuous energization and upon changes in environmental factors such as temperature and humidity.
