Abstract
An image forming method comprising a fixing step of fixing a toner image to a recording material while nipping and conveying the recording material, on which the toner image has been formed, by a fixing nip portion, wherein the toner comprises a toner particle comprising a toner base particle and an organosilicon polymer on a surface thereof, the organosilicon polymer has a structure represented by R—SiO, where R is an C1 to C6 alkyl group or a phenyl group, the organosilicon polymer has convex portions formed on an outer surface thereof, and the convex portions satisfy specific relationships, and a contact pressure σ (MPa) of the pressure member and the fixing film and a storage elastic modulus G (MPa) of the toner at a temperature of a surface of the fixing film when the recording material is nipped and conveyed by the fixing nip portion satisfy specific relationships.
