Abstract
A heating device includes a cylindrical film configured to be rotated about an axis, a heater including a substrate that extends along a longitudinal direction parallel to the axis, and a heater element on the substrate and facing an inner surface of the cylindrical film. A heat conductor extends along the longitudinal direction and has first and second surfaces. A first portion of the heat conductor contacts the substrate and a second portion of the heat conductor has a groove in the first surface. A temperature sensing element is disposed at a position on the second surface at a position opposite the groove.
