Abstract
An image forming method has steps of transferring a toner image formed on an image bearing member onto an intermediate transfer member and simultaneously transferring and fixing the toner image on the intermediate transfer member onto a recording medium. The toner contains a binder resin and a colorant, and has a storage elastic modulus (G′) of 2×102 to 6×103 Pa at a temperature at which a loss elastic modulus (G″) reaches 1×104 Pa, and the simultaneous transfer and fixing is conducted using a transfer and fixing unit which has a nip between a fixing roll coated with an elastic member and a heat-resistant belt laid across support rolls, and the heat-resistant belt is urged against the fixing roll and the elastic member of the fixing roll is twisted at an exit of the nip with a pressure roll mounted inside the heat-resistant belt.
