PURPOSE:To stabilize image densities and to obtain good images without generating fogging, etc., by sticking fine powder of >=1 kinds selected from conductive particles, inorg. filler particles or charge control agent on the surface of a carrier coated with a resin. CONSTITUTION:The fine powder of >=1 kinds selected from the conductive particles, the inorg. filler particle on the charge control agent is stuck onto the surface of the carrier coated with the resin. The shape of the resin-coated carrier may be spherical or may be spherical or may be unshaped and the carrier is so formed that the fine particles are stuck uniformly to the carrier surface. The fine powder to be adhered is of >=1 kinds selected from the conductive particles, the inorg. filler particles on the charge control agent which act to exert the effect of imparting an excellent development characteristic to toners on the resin carrier and to accelerate dispersibility, thereby assisting the formation of uniform images. The good images which are stable in image density and obviate the generation of the fogging, etc., are obtd. in this way. |
