Abstract
An image forming apparatus includes a fixing unit including a roller, a heating rotary member heating the roller, and a backup member forming a nip portion, a temperature detection unit detecting a temperature of the heating rotary member, and a control unit for controlling power so that the detected temperature is maintained at a target temperature, wherein a print job includes a first step in which the unfixed toner image is formed on the recording material, a second step in which fixing processing is executed, and a third step in which the fixing unit is cleaned, and wherein the third step is executed following the second step, and in the third step, while the target temperature is set higher than the target temperature in the second step, the roller and the heating rotary member are rotated in a state where no recording material is present at the nip portion.
