ABSTRACT:
In the image forming apparatus according to the invention, a fixer fixes toner on the sheet and presses the sheet, and a media sensor measures a thickness of the sheet before pressurization and a thickness of the sheet after pressurization. Then, by calculating an amount of heat used if the fixer fixes the toner on the sheet on the basis of the measurement result, a control unit is able to control the temperature of the fixer on the basis of the calculated amount of heat. In this manner, it is possible to appropriately calculate an amount of heat per unit area required to fix toner on the sheet.
