PURPOSE:To improve the power to apply friction electrified charge to a toner, a life as a developer, stability in environment of a high temp. and high humidity or low temp. and low humidity, etc. by coating a carrier with a metallic complex of 8-oxyquinoline. CONSTITUTION:The metallic complex of 8-oxyquinoline expressed by the formula is incorporated into a carrier surface to obtain an intended carrier material. The more specific coating method is exemplified by a method of dissolving or dispersing the metallic complex of 8-oxyquinoline into a solvent and immersing the carrier in such soln. or dispersion, a method of mixing the powder metallic complex of 8-oxyquinoline with the carrier in a dry process or a method of dispersing the metallic complex of 8-oxyquinoline with a resin (e.g.; acrylic resin, melamine resin) at about 0.1-20pts.wt. for each 100pts.wt. the resin then mixing the same with the carrier. |
