Abstract:
When an infra-red heater is to be taken out from a fixing device for maintenance of the infra-red heater, screw-fastening is first released and one holder is extracted from a holding member. The infra-red heater is then pulled out from the side the holder was extracted from. This process is then reversed when a new or repaired infra-red heater is to be mounted on the fixing device. There is a pressure member in pressure contact with a flexible fixing member. The surface area of the contacting member facing the pressure member is variable.
