Abstract
An image forming apparatus has an image forming unit for forming an unfixed image on a recording material, an image fixing device for fixing the unfixed image on the recording material, the image fixing device having at least one heater, and a power supply for supplying electric power to the heater. The power supply supplies electric power to the heater until the fixing device reaches a predetermined temperature possible to start copy after a power source of the image forming apparatus is turned ON, and preparation of the image forming unit permitting image formation on the recording material is effected before the fixing device reaches the temperature possible to start fixing after the power source is turned ON, and, during the preparation, the power supply reduces the electric power supplied to the heater, and, after the preparation, the power supply increases the electric power supplied to the heater.
