Abstract
An image forming apparatus comprises a fixing device comprising a heater for heating a sheet on which an image is formed and a non-volatile memory in which characteristic information of the heater is stored. The fixing device is replaceable. In a case where the fixing device is replaced, the image forming apparatus starts to supply power to the heater before completing to read the characteristic information from the fixing device replaced. Due to this, the image forming apparatus can promptly heat the heater of the fixing device than before.
