Carrier for electrostatic latent image developer

Abstract

Abstract PURPOSE:To enable the formation of a stable image of high quality by coating the surface of a carrier with silicone resin contg. an organotin compound and electrically conductive fine powder. CONSTITUTION:The surface of a carrier is coated with silicone resin contg. an organotin compound and electrically conductive fine powder. The silicone resin may be silicone varnish, alkyd modified silicone varnish or epoxy modified silicone varnish. A proper quantity of electric charges having desired polarity can be easily provided to a toner by changing the amount of the organotin compound as a curing catalyst in the resulting silicone resin layer. A usable low resistance substance is an org. substance such as carbon black or an inorg. substance such as boride, carbide, nitride, oxide or silicide. Thus, a stable image of high quality can be formed without wastefully spending the toner.
