ELECTROPHOTOGRAPHIC DEVELOPING TONER AND IMAGE FORMING METHOD

PURPOSE:To provide a color image forming method capable of forming color images having good color reproducibility without generating color clouding at edges and further a color developer which does not generate color clouding at the edges. CONSTITUTION:This developer is used for the image forming method of forming the color images by having at least LED exposure systems 6 to 9 and plural developing devices 10 to 13 and forming the color images by repeating development plural times by a reversal development system on a photoreceptor, then integrally transferring the color images onto a transfer material and fixing the color images contains at least a resin and pigments. The developer described above contains toners consisting of >=74number% pigment particles existing in the toner particles having a major axis of Xnm or below, when the light emission wavelength of LED is defined as Xnm,
