Abstract
A device for monitoring the temperature of a moving surface, particularly the outside surface of a heated roller in a toner fusing apparatus, includes a roller which rolls on the surface as it moves. The roller is virtualy entirely made up of two thermocouple materials. Because the materials themselves directly engage the surface being monitored, the device has a fast response to temperature change of the surface.
