Abstract
The heater to be used for an image heating apparatus includes a substrate, and first and second heat generation lines that are provided on the substrate along a longitudinal direction of the substrate, and are each divided into a plurality of heat generation blocks that can be mutually independently controlled, in the longitudinal direction, wherein in the plurality of heat generation blocks in the second heat generation line, a heat generation block is provided that overlaps one heat generation block in the first heat generation line in the longitudinal direction, and has a different heat generation distribution in the longitudinal direction, and can be independently controlled. Accordingly, the heater can form a heat generation distribution that is suitable for various paper sizes.
