Title:
CONDUCTIVE ROLL
Document Type and Number:
Japanese Patent JP3240759
Kind Code:
B2
Abstract:
PURPOSE: To disperse the distribution of voltage when voltage is applied on a conductive roll and to prevent dielectric break down by using an ionic conductive elastic material having specified volume resistivity to form the base layer of the conductive roll so that the base layer has medium resistance.
CONSTITUTION: This conductive roll is produced by forming a base layer 12 by using an ionic conductive elastic material around the shaft body 10, and forming an electrode layer 14 on the base layer 12 by using a synthetic resin with an electron conductive material compounded. The ion conductive elastic material of the base layer 12 consists of a specified elastic material into which an ionic conducting agent is added to control the volume resistivity to 106-109Ωcm. The ionic conducting agent is, for example, trimethyl octadecyl ammonium perchlorate, benzyltrimethyl ammonium chloride. As for the elastic material, urethane rubber, epichlorohydrin rubber, or acrylonitrile butadiene rubber is used.
