<p>A fixing device (1) and a digital copying apparatus (101) such that the time from the start command for image formation to the end of fixing is short and the required consumed power is low. The fixing device includes a cylinder (2) made up of a thin metallic sheet and an exciting coil (11) provided in the cylinder and adapted to generate eddy current. When the power is turned on, the remainder of the subtraction of the power consumed by the other devices than the fixing device from the supplied power is fed to the exciting coil to heat a heating roller of the fixing device. While the units of the copying apparatus and the auxiliary devices added to the copying apparatus are started sequentially, the remainder of the subtraction of the power consumed by the units and auxiliary devices from the input allowable power is fed to heat the heating roller to a fixable temperature in a short time, thus shortening the first copying time.</p> |
