PURPOSE:To obtain an electrostatic charge image developing carrier and developer excellent in durability and electrification stability, high transfer efficiency of the toner and excellent storage stability with which sharp picture images with high picture image density and little fogging is obtd. CONSTITUTION:At least part of the core material of the electrostatic charge image developing carrier is coated with the resin containing copolymers of vinylidene chloride and at least one kind of monomer having unsatd. double bonds copolymerizable with that vinylidene chloride. The copolymer consists of (a) 70-30mol% vinylidene chloride, (b) 20-60mol% acrylonitrile and/or acrylnitrile deriv. and (c) 0-40mol% of monomer having unsatd. double bonds copolymerizable with these components. |
