ABSTRACT:
An image forming method comprises: fixing an image formed by a toner on a record sheet in a nip member formed by a pressurizing member which is compressibly contacted against a heating fixing rotor having an elastic body layer formed on an endless periphery surface capable of orbitally moving and which creates locally a large distortion occurred in the elastic body layer in vicinity of outlet thereof,wherein the toner includes at least two metal salts having different valence and has a relationship given by the Formula (1).in-line-formulae description="In-line Formulae" end="lead"?2.0≧a≧0.1in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1.0≧b≧0.01in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?7.5≧a/b≧1.1 Formula (1)in-line-formulae description="In-line Formulae" end="tail"?wherein a (mass %) is defined as a content of a metal salt which is contained at a highest content in total toner mass and b (mass %) is defined as a content of a metal salt which is contained at a second-highest content in the total toner mass, and mass values of a and b represent anhydride reduced values.
