An image forming method including steps of forming a latent electrostatic image on an image bearing member, developing the latent electrostatic image with a development agent containing toner to obtain a toner image; transferring the toner image onto a transfer medium; fixing the toner image thereon; wherein the fixing is executed by a fixing device containing a heating roller; a fixing roller; a toner heating medium and the fixing roller; and a pressure roller wherein the toner contains a toner binder containing a crystalline resin containing a polyester resin A; a non-crystalline resin containing a non-crystalline resin B and a non-crystalline resin C, and a complex resin, wherein the toner has a main peak in a range of from 1,000 to 10,000 in the molecule weight distribution as measured for a component soluble in tetrahydrofuran by gel permeation chromatography with a half value width of 15,000 or less.
