ABSTRACT:
A heater includes a substrate; a heat generating resistor on the substrate to generate heat when supplied with electric energy; a pair of electrodes for supplying the energy to the heat generating resistor; and a resistance adjustment portion for adjusting the resistance between the electrodes. The resistance adjustment portion adjusts the resistance while maintaining uniform electrical conductivity between the electrodes and the heat generating resistor.
