PURPOSE:To get rid of toner scattering and make a fixing quality excellent and also prolong the wear lives of a photosensitive body, a cleaning blade or the like at a toner containing an organic magnetic body, by using a toner whose saturation magnetic moment as a toner is more than a specific value. CONSTITUTION:At a toner consisting of binding resin and a magnetic body, the one whose magnetic body is an organic magnetic body and moreover, whose saturation magnetic moment is more than 5emu/g, is used. As for the organic magnetic body used in this invention, a ferrocene polymer or the like which is an organic metal polymer, is listed. As for this ferrocene polymer, either of a ferrocen polymer having a ferrocene core as a principal chain and a ferrocen polymer having a ferrocene core as a side chain can be used, and when the polymer whose ferrocene core is contained in the principal chain is exemplified, a polymer shown in the following usual formula is listed. |
