FIXING HEATER, FIXING APPARATUS AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize a temperature detection element for simply carrying out temperature detection of a fixing heater by forming it by a thick film printing and calcining it. SOLUTION: Each of electrodes 21 and 22, connecting parts 23 and 24 and a temperature detection element 25 are integrally formed simultaneously by carrying out the thick film printing using a screen mask on a substrate 11 with an alloy of silver (Ag) and palladium (Pd) and a desired shape is obtained by calcination. Resistance value of the temperature detection element 25 is varied corresponding to the temperature variation in order to detect the temperature of an exothermic resistor formed on the backside of the substrate 11 on which the temperature detecting element 25 is formed.
