COMPOSITE CARRIER FOR ELECTROPHOTOGRAPHIC DEVELOPER

摘要

PURPOSE:To maintain satisfactorily high image quality and to provide superior developing power by using a composite carrier made of a mixture of a granular carrier with a flat carrier. CONSTITUTION:A composite carrier is made of a mixture of 30-95pts.wt. granular carrier having 10<7>-10<11>OMEGA.cm resistivity with 70-5pts.wt. flat carrier having 10<3>-10<6>OMEGA.cm resistivity. The flat carrier is obtd. by flattening a granular carrier by physical crushing.
