Abstract
The heating apparatus includes a first temperature detecting element disposed at least in proximity to a moving member, a second temperature detecting element for detecting the temperature of the heating member or the atmospheric temperature of the apparatus, a controlling portion for controlling electric power supply to the heating member, and a judging portion for judging on the basis of the result of the detection by the second temperature detecting element whether the electrical energization of the heating member should be effected before the start of the movement driving of the moving member, whereby temperature control is effected accurately and at the same time, the slip of the moving member, any increase in driving torque, etc. are prevented.
