Abstract
A fixing device includes a tubular member extending in an axial direction, a heater, and a support. The heater has a first surface in contact with an inner surface of the tubular member. The first surface faces in a first thickness direction. The heater includes a substrate. The substrate includes a cut section at which the substrate is disconnected from a base material. The cut section is positioned at an end portion of the substrate in a first lateral direction. The substrate extends longitudinally along the axial direction. The support is in contact with the inner surface of the tubular member. The support includes a projection longitudinally overlapping at least a portion of the cut section and a low section longitudinally offset from the projection. The projection extends further in the first thickness direction than the low section and the first surface.
