ABSTRACT:
The present invention provides an image forming method including the steps of: forming an electrostatic latent image on a latent image holding member; developing the electrostatic latent image by using a color toner to form a toner image; transferring the toner image onto a recording material; and fixing the toner image to the recording material by a heat fixing device including a heating member in contact with the toner image. In the method, the color toner contains at least a binder resin, a colorant and wax, the wax having a molecular weight distribution measured by GPC, which has a ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn) of 1.45 or less, and a solubility parameter (SP value) of 8.4 to 10.5. If the contact angles between the wax and the heating member at 100.degree. C. and 200.degree. C. are A and B, respectively, the contact angles A and B satisfy the following relations:
