To provide an image forming method capable of achieving low-temperature fixing in a high-speed system and preventing white-out in an image area by suppressing toner filming on an image carrier. A system speed is 500 to 1700 mm / sec, and a toner includes a toner base and an external additive, and the toner base includes a crystalline polyester resin, an amorphous resin, a wax, The amount X (parts by weight) of the external additive is 0.30 to 0.55 parts by weight with respect to 100 parts by weight of the toner base, and the FT-IR (Fourier transform infrared spectroscopic analysis measurement of the toner) The peak ratio of the crystalline polyester resin measured by the ATR method (total reflection method) is C, W is wax, and R is amorphous resin. , W / R satisfies the relationship of the following formula (1). 0.36 ≦ (2.77 × C / R + 1.97 × W / R) /X≦1.85 Formula (1) [Selection] Figure 1 |
