Abstract
The image heating apparatus includes a heater having first and second and heat-generation segments each having a plurality of spaced-apart heat generating parts therein in the longitudinal direction respectively. The heat generating parts each have first and second electro-conductive patterns provided along the longitudinal direction on a substrate and overlapping in the longitudinal direction, and a heat generating resistor which electrically connects the respective overlapping regions of the first electro-conductive pattern and the second electro-conductive pattern with each other and generates heat by supplied electric power. It simultaneously prevents the temperature in a non-sheet feeding portion from rising and secures fixing properties in the gap between the adjacent heat generating parts.
