Claim 5:
6. An image heating device heating an image formed on a recording material, the image heating device comprising:
a tubular film; and
a heater provided in an internal space of the film, the heater includes,
a substrate,
a first heating block provided on the substrate and configured to generate heat by electric power supplied thereto,
a second heating block provided on the substrate at a position different from the position of the first heating block in a longitudinal direction of the substrate and configured to generate heat by electric power supplied thereto,
a first temperature sensor provided at a position corresponding to the first heating block in the longitudinal direction of the substrate,
a second temperature sensor provided at a position corresponding to the second heating block in the longitudinal direction of the substrate,
a first conductive pattern provided on the substrate, the first conductive pattern is electrically coupled to the first temperature sensor at a first end of the first conductive pattern, and
a second conductive pattern provided on the substrate, the second conductive pattern is electrically coupled to the second temperature sensor at a first end of the second conductive pattern,
wherein a second end of the first conductive pattern and a second end of the second conductive pattern are arranged in a direction perpendicular to the longitudinal direction of the substrate.
