Abstract
An image forming apparatus with an image forming section which forms an toner image on a transported sheet; a fixing section which includes a heat source and fixes the toner image on the sheet; a coupling unit which electrically couples the image forming apparatus main unit and the fixing equipment to each other; and a circuit which detects the temperatures of various portions of the fixing equipment, controls the energization condition to the heat source depending on the temperature detection results and stops the energization of the heat source if a temperature beyond a predetermined temperature range is detected by either the first or second temperature detection element, if the coupling unit is disconnected, or if the second temperature detection element is broken.
