Abstract

PURPOSE: To form good copied images having no fog and high resolution in an wide allowable range of toner to carrier mixing ratio, by using insulating magnetic carrier prepared by dispersing magnetic fine particles into an insulating resin.
CONSTITUTION: A resin and magnetic fine particles undergo melting, follwed by mixing, cooling finely pulverizing, and classifying. A particle size of 10W25 μ is used for carrier. The use of such insulating magnetic fine carrier enable good copied images of high resolution to be formed.
