ABSTRACT:
A radiant heat fuser for an electrostatic copying machine in which heat for fusing the delicate toner image on top of a sheet is applied using a top heater of radiant type, and background heat to the underside of the sheet is provided by means of heat-absorbing and -radiating elements positioned in the fuser bed and arranged to absorb radiant heat while no sheet is being fed and to radiate and convect heat to the underside of the sheet as it passes through the fuser. The control of the temperature of these heat-absorbing and -radiating elements is achieved by way of a cooling air system throttled in accordance with temperature-responsive deformation of the heat-absorbing and -radiating elements some of which are accordingly of bimetallic form.
