PURPOSE:To obtain a image which is free from clouding in color by incorporating an org. magnetic material into the toner. CONSTITUTION:This color toner contains the org. magnetic material and consists of at least the org. magnetic material, coloring agent and binder resin. The org. magnetic material refers to an org. compd. (including an org. metal complex) and high-polymer compd. (including a high-polymer org. metal complex) which are magnetized at the intensity corresponding to an external magnetic field by the specific chemical structure and exhibit magnetization characteristics of paramagnetism or ferromagnetism. More specifically said material is preferably iron (II, III)-poly (2, 6-pyridine dimethylidene nitrohexamethylene nitromethylidenate). The content of the coloring material to be used is adequately 1-20wt.%, more preferably 3-7wt.% of the total weight of the toner. The sharp image which is free from clouding in color is thereby obtd. |
