Abstract
An image forming apparatus includes a noncontact heating device, a pressurizing and heating mechanism, and a control unit. The control unit switches an operation of the pressurizing and heating mechanism based on gloss level information of a recording medium. According to the image forming apparatus, assuming that a temperature of the recording medium after noncontact heating is T1, a temperature of the recording medium after pressurizing and heating is T2 and a toner concentration after noncontact heating is Tc1 when the gloss level information shows high gloss, and assuming that a temperature of the recording medium after noncontact heating is T3 and a toner concentration after noncontact heating is Tc2 when the gloss level information shows low gloss, the conditions of T1<T2, T1<T3, and Tc1<Tc2 are satisfied.
