MULTICOLOR IMAGE FORMING METHOD AND TONER USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multicolor image forming method which is good in the color reproducibility over the entire part and is wide in a color reproduction range and reproduces a red region and bluish purple region in particular even in the image forming method using a contactless heat fixing system and toners used for the same and to provide the multicolor image forming method which does not give rise to a change in the stability of the formed images and particularly a change in the images in spit of exposure to light and the toners used for the same. SOLUTION: The first layer among the multicolor layers on an improving holding body just prior to fixing in the multicolor image forming method using the contactless heat fixing system is the yellow toners and the respective toners to be used consist of at least binder resins and pigments. The yellow toners contain pigments of a benzimidazolone system and the cyan toners containβcopper phthalocyanine. The magenta toners contain naphthol Carmine F6B or naphthol Carmine F6B and naphthol Carmine FBB.
