PROBLEM TO BE SOLVED: To provide a full-color image forming method which prevents a local transfer defect (wormhole and firefly) caused in transfer and a reproducibility defect of an image due to toner and dust as an image forming method which uses an intermediate transfer system, toner for full-color electrophotography used for he method, and a manufacturing method for the toner. SOLUTION: An intermediate transfer body has a <=0.4 surface friction coefficient, a 10<9> to 10<13> Ω.cm intrinsic volume resistance value, and <=3 μm surface roughness. The toner for full-color electrophotography in use has its circularity prescribed as specified and also has a fluidity imparting agent, and a >=70% electrostatic charging rise rate. The particle size of the fluidity imparting agent is also prescribed as specified. The particulate content is also determined. Further, when the toner is manufactured, a toner raw material is primarily pulverized by a jet pulverizing machine of specific constitution and the primarily pulverized body is secondarily pulverized by a pulverizing and classifying device of specific constitution. |
