Abstract

PURPOSE: To reduce the amount of toner film to be accumulated on the surfaces of carrier particles and the amount of carrier coating material to be removed by abrasion and peeling during successive copying, by coating the carrier particles with a composite of a fluoropolymer and an inorganic filler.
