Abstract

In an image forming apparatus including an image forming unit which forms an image in which toner containing a wax is used on a recording material, and a fixing device which heats the toner image formed on the recording material at a nip portion which nips and conveys the recording material, when the fixing device heats the recording material on which a toner image having a maximum toner-carrying amount of toner is formed, when a temperature of a surface of the toner layer reaches a temperature at which an endothermic amount indicates a peak in a relationship between a temperature of the toner and the endothermic amount, a condition of the fixing device at the nip portion is set so that a temperature of an interface between the toner and the recording material is lower than a temperature of a surface of the toner.
