An image forming method using an oilless fixing method provides an image forming method capable of preventing defective paper ejection and forming a good image even when a toner containing carbon black is used. A toner containing toner particles containing a binder resin, carbon black, and a release agent has a mass average particle diameter of 3.5 to 9.5 μm, and has a ratio of (dielectric loss factor ε ″ / dielectric constant ε ′). ) Is 0.008 to 0.018 at a frequency of 5 × 10 4 Hz and 0.006 to 0.016 at a frequency of 10 5 Hz, and the mass average molecular weight (Mw) is 200000 ９００900,000, the car's fluidity index is 55-98, and the car's squirtability index is 70-98, and the release agent is contained in 2 to 20 parts by mass in 100 parts by mass of the toner particles.
