Abstract:
1. An image forming apparatus comprising: an image forming portion including an image bearing member for bearing an electrostatic image and an developing device for developing the electrostatic image on said image bearing member, for forming a toner image to a recording material; a heater, which heats said image bearing member; a heating fixing device, which heat-fixes the toner image on the recording material; a capacitor, which stores an electricity supplied from a commercial power source; a distributor, which distributes power of said capacitor to said heat fixing device and said heater in a warming-up time for increasing a temperature of said heat fixing device to a predetermined temperature; and control means for controlling said distributor to make a distribution rate of the power of said capacitor to said heat fixing device larger than a distribution rate of the power of said capacitor to said heater when an atmospheric temperature is lower than a predetermined temperature, and to make the distribution rate of the power of said capacitor to said heater larger than the distribution rate of the power of said capacitor to said heat fixing device when the atmospheric temperature is higher than or equal to the predetermined temperature.
