Abstract (en)
[origin: US4585325A] A fixing roller device having a pressure roller and a heating roller as the fixing roller. Heating elements sealed into glass cylinders are located inside the heating roller, parallel to a roller axis. One heating element consists of a coil in a middle zone of the heating roller, while the other heating element has two coils in edge zones of the heating roll. Two temperature sensors are arranged respectively in the middle of the heating roller and near one of the end faces of the heating roller, at a small distance from the heating roller surface, and are connected to a control system which controls the current supply to the heating elements and cuts this supply as soon as the temperatures measured by the temperature sensors reach predetermined intended values.
