An image forming apparatus which can shorten a first printing time in accordance with a recording mode without increasing electric power consumption is provided. When a reception signal is absent, if a copy key has been depressed, the image forming apparatus is switched to a copy mode, and temperature control is started by supplying a heater of a thermal fixing device with electric power. When the user operates a start key to start copying after setting an original and copying conditions, it is determined if the heater has reached a fixable temperature. If the result of the determination is affirmative, a copying operation is completed by performing image formation and fixing on a recording sheet. When a reception signal is present, image data is received, and after storing the image data in an image memory, temperature rise control of the heater is started.
