Heizvorrichtung zur Fixierung von Information auf ein Informationsaufzeichnungsmedium

摘要

A heating element (30) for a device for fixing images in photocopiers or information printed by a printer on media (12) having different formats is formed by a layer of resistive material having a negative temperature coefficient (NTC), so that, in the portion of the heating element (30) not covered by a medium of any smaller format, the quantity of heat supplied and the temperature of the heating element are automatically adjusted without the use of a special control circuit.
