PROBLEM TO BE SOLVED: To solve problems such as fixing bulging, scattering, and tailing caused by minute temperature distribution unevenness of a fixing device, high in-plane uniformity of solid image density, line image scattering, An object of the present invention is to provide a fixing method free from image defects such as tailing. In a section from one end to the other end of the maximum image-passing area of an image on a recording material, the magnetic resistance of the core is the magnetic resistance of the conductive layer and the magnetic resistance of the area between the conductive layer and the core; A fixing device having a combined magnetic resistance of 30% or less is used. As the toner, a toner having an average circularity X of 0.940 to 0.990, a pressure density Y of 25.0 to 55.0, and satisfying the following formula (b) is used. 345≰333X + Y≰370 (b) [Selection] FIG. |
