Abstract: PURPOSE:To obtain a developer capable of maintaining initial high quality image in repeatingly copying over a long time and hardly affected by temp. and humidity by using a carrier made by coating a part of the core material with a chlorinated vinyl chloride resin and a toner containing an acidic carbon black. CONSTITUTION:The chlorinated vinyl chloride resin applied on the carrier is obtained by further chlorinating a vinyl chloride polymer. If only a resin contains the chlorinated vinyl chloride resin, a composition made by blending another resin or the like with the resin is also used as the coating agent for the carrier core material and for instance, a material blended with a fluororesin such as vinylidene fluoride, vinylidene fluoride-tetrafluoroethylene copolymer is exemplified. The acidic carbon black is used as the coloring agent contained in the toner. The acidic carbon black is obtained by boiling carbon black with water and adjusting pH to <=6 and particularly the acidic carbon black having pH2-6 is preferably used.
