Abstract

PURPOSE: To obtain carrier having stable friction charging characteristics, high durability and a long life by covering the surfaces of nuclear particles for the carrier with a reaction product (resin) of an epoxy group-contg. compound and an amine type compound.
CONSTITUTION: A compound having an epoxy group represented by formula I (where l is an integer of 1W15) and an amine type compound represented by formula II (where A is alkyl, alkenyl or aryl, each of A' and A" is H, alkyl, alkenyl or aryl, and A' and A" may be cyclized to form an N-contg. heterocyclic ring) are mixed, pulverized, melted by heating, and reacted. The resulting resin is dissolved in a solvent such as alcohols of ketones, and this soln. in coated onto the surfaces of nuclear particles for carrier to form about 0.1W30, preferably 0.2W20μ coats. Thus, carrier is obtd. This carrier 100 parts is blended with toner about 1W10 parts to give a developer.
