Abstract
PURPOSE:To obtain an image which is stable for a long period of time by using a silicone resin as a coating resin and incorporating conductive particles selected from a group consisting of titanium oxide, zinc oxide and tin oxide into the coating resin. CONSTITUTION:The silicone resin is used as the coating resin for a coated carrier having the resin coating layer dispersed with the conductive particles on the surface of a carrier core. One or >=two kinds selected from the conductive particles of the group consisting of the white titanium oxide, zinc oxide and tin oxide are used for the conductive particles. Since the good quantity of electrostatic charge is thereby maintained even if the carrier is used for a long period of time, the ground stain and bristle trace of the image are obviated. The excellent image is thus obtd.
