ABSTRACT:
A recording apparatus such as a facsimile apparatus comprises a first control unit to perform a control regarding the generation of dot data, a second control unit for controlling the recording operation, a fan to reduce a temperature in the apparatus, a heat fixing device having a heater, and detectors such as thermistors for detecting temperatures at a plurality of positions near the fixing device. Each of the first and second control units generates a first control signal to control the rotation of the fan on the basis of detection outputs from the thermistors. The heat fixing device has a cylindrical endless film made by polyimide or the like whose inner surface is come into contact with the heater and a pressure roller which is come into contact with the outside of the endless film. A recording paper is sandwiched between the film and the pressure roller and passes therebetween.
