Abstract
An image forming apparatus includes an image forming portion, a fixing unit including a fixing member, a heating member, and a temperature detection portion, and a control portion configured to execute warm-up processing. If a temperature of the heating member at a first timing in a period of time in which the heating member is being heated in the warm-up processing is a first temperature, a temperature of the heating member at a second timing that is in the period of time and that is later than the first timing is a second temperature, and a temperature of the heating member at a timing different from the first timing and the second timing is a third temperature, the control portion is configured to change a fixing condition used in the job, based on the first temperature, the second temperature, and the third temperature.
