The image heating apparatus includes first and second lines having a first and second heat generation blocks, the first and second lines being disposed at different positions in a transverse direction, wherein the first and second lines are arranged so that a whole of first heat generation block in the first line and a whole of second heat generation block in the second line overlap with each other in the longitudinal direction, and a whole of second heat generation block in the first line and a whole of first heat generation block in the second line overlap with each other in the longitudinal direction. By the virtue of the present invention, it achieves to be capable of suppressing a temperature rise in a non-sheet feeding area in a case of printing a sheet smaller in size than a maximum size supported by the image heating apparatus.
