Abstract
An image forming method makes the warming-up time short, enables the formation of high-quality images even when fixing is performed continuously at high speed, and restrains degradations of the image quality, such as non-uniformity of gloss and non-uniformity of coloration even under high-temperature and high-humidity conditions. The method uses a toner that is wide in fixing range and is especially excellent in low-temperature fixing property. The method contains a process of melting and thereby fixing a toner image formed by unfixed toner, by heating a heating member that is in contact with the toner image. The surface of the heating member or its vicinity that is in contact with the toner image generates heat, and the toner contains at least a colorant and a binder resin having a crystalline resin with a number average molecular weight of 1500 or more as the main component.
