Abstract
An image forming apparatus, including an image forming unit, a fixing unit with a heater, an end temperature sensor to detect a temperature in an end area an end area of the fixing unit, and a controller, is provided. The controller is configured to perform a width obtaining step to obtain the width of the sheet, a temperature obtaining step to obtain the detected temperature of the fixing unit, a comparison step to compare the detected temperature with a threshold, a cooling step to let the end area of the fixing unit cool down when the detected temperature is one of higher and equal to the threshold, and a threshold-setting step to set one of a first value and a second value to be the threshold depending on the width of the sheet obtained in the width obtaining step.
