<P>PROBLEM TO BE SOLVED: To achieve a high-speed temperature rise in a plate-like heater, and to restrain the elevation of a temperature in a non-paper passing part. Ž<P>SOLUTION: The resistor paste of an Ag/Pd alloy or the like is baked at a high temperature to form a strip heating resistor 12 formed of a thick film having a predetermined resistor value in the longitudinal direction on a long flat ceramic substrate 11. Electrodes 15, 16 are formed at both ends on the ceramic substrate 11. The electrode 15 has conductor patterns 15a, 15b and the electrode 16 has conductor patterns 16a, 16b which are integrally formed in non-contact states with the heating resistor 12 from a position in the transverse direction of the ceramic substrate 11 of the electrodes 15, 16. PTC (Positive Temperature Coefficient) heating units 171, 172 are formed between the conductor patterns 15a, 16a and the heating resistor 12, and NTC (Negative Temperature Coefficient) heating units 181, 182 are formed between the conductor patterns 15b, 16b and the heating resistor 12.
