  • Conductive member for OA equipment
    Patent number: 7226551
    Abstract: It is an object of the present invention to provide a conductive member for use in OA equipment which shows very stable conductivity in the volume resistivity range of 105 to 1012 ?·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 and which will not stain photoconductors due to bleeding or blooming. The present invention provides a conductive member for OA equipment, which is obtainable by molding a composition comprising a non-ether-based polyurethane and bis(trifluoromethanesulfonyl)imidolithium.
    Type: Grant

  • Conductive member for OA equipment
    Patent number: 6936184
    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 105 to 1012 ?·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.
