Abstract:
An image forming method, comprising:heating and pressing a toner image onto a recording material by heat-pressure means to form a fixed image on the recording material wherein said heat-pressure means comprises (i) magnetic flux generating means, (ii) a rotatable heating member having a heat generating layer capable of heat generation by electromagnetic induction and a release layer and (iii) a rotatable pressure member forming a fixing nip with the rotatable heating member, so that the toner image on the recording material is fixed under heat and pressure at the fixing nip under a temperature distribution around the fixing nip satisfying: Z3&lE;Z21, wherein Z1 is a temperature at a position before entering the fixing nip; Z2 is a temperature at a position after passing the fixing nip and Z3 is a temperature at a position before causing heat generation, respectively, of the rotatable heating member, by pressing the rotatable pressure member against the rotatable heating member via the recording material, the toner image is formed of a toner comprising toner particles each containing at least a binder resin and a colorant, the toner has a moisture content of at most 3.00 wt. %, and the toner has a storage modulus at 110Â° C. of Gâ€² (110Â° C.) and a storage modulus at 140Â° C. of Gâ€² (140Â° C.) satisfying: Gâ€² (110Â° C.)&lE;1.00Ã—106 dN/m2, and Gâ€² (140Â° C.)&gE;7.00Ã—103 dN/m2.
