Abstract
A carrier for developing electrostatic latent images is disclosed, which comprises a core material at least a part of which is coated with a resin containing a copolymer comprised of vinylidene chloride and at least one monomer having an unsaturated double bond and being copolymerizable with vinylidene chloride, wherein the copolymer is comprised of (a) from 70 to 30 mol % of vinylidene chloride, (b) from 20 to 60 mol % of acrylonitrile and/or an acrylonitrile derivative, and (c) from 0 to 40 mol % of a monomer having an unsaturated double bond and being copolymerizable with components (a) and (b). An electrophotographic developer containing the carrier and an electrophotographic developing process using the developer are also disclosed.
