(57) [Problem] To increase the process speed and suppress the occurrence of hot offset to form a good image for a long period even when performing image formation using a small-diameter heat fixing roll. To provide an image forming method. SOLUTION: A step of forming an electrostatic latent image on an electrostatic carrier, a step of forming a toner image on the electrostatic carrier using a developer, and a step of transferring the toner image on a transfer body Fixing the toner image transferred on the transfer body by a heat fixing roll and a pressure member pressed against the heat fixing roll, (1) A magnetic one-component developer is used as a developer, the amount of free magnetic powder contained in the developer is set to 0.1 vol% or less, and (2) the outer diameter of the heat fixing roll is reduced. 40mm or less, process speed 200m m / s or more. |
