An image forming apparatus and an image forming method are provided which form high-quality fixed images having no fogs and the like defects, in which apparatus and method a toner entering a pressure-contact area between rollers is prevented from scattering. A control is performed on preheating conditions for preheating an unfixed toner image on a recording medium, which unfixed toner image indicates a toner image transferred but not yet fixed, and a control is further performed such that an amount of toner attached to the recording medium at a coverage rate of 100% is 0.4 mg/cm2 or less, with the result that the toner is prevented from scattering when the recording medium carrying the unfixed toner image passes through a pressure-contact area formed between a heating roller and a pressurizing roller in a fixing step.
