摘要： A magnetic brush developer for electrophotography by the reversal development system where a uniform positive charge is imparted to a photoconductive insulator, the insulator is irradiated with a light image to form an electrostatic latent image and the latent image is developed and visualized by a positively charged toner. The developer comprises a carrier of granulated magnetite particles, the surfaces of which are coated with a thermosetting resin containing a fine fluoropolymer powder and a fine magnetite or carbon black powder dispersed therein. When this developer is used, adhesion of the toner to the sleeve is not only prevented at the initial stage of printing but also after continuous printing, and even if continuous printing does conducted, the charge quantity is not reduce, therefore print quality does not degrade.
