1. A device configured to fix toner to a sheet, the device comprising:
a tubular body configured to be in contact with the sheet moving in a first direction, the tubular body being rotatable about an axis extending along a second direction orthogonal to the first direction;
a heater comprising a heat generator, a first surface, and a second surface on an opposite side of the first surface, the first surface being in contact with an inner surface of the tubular body; and
a heat conduction section in contact with the second surface of the heater and configured to transfer heat generated from the heat generator, wherein
the heat conduction section comprises:
a first heat transfer section in contact with the second surface of the heater; and
a second heat transfer section in contact with a surface opposite to the heater with respect to the first heat transfer section, the second heat transfer section having lower thermal conductivity and a larger heat capacity per unit length in the second direction compared to the first heat transfer section,
the second heat transfer section defining a recess on a surface of the second heat transfer section that is opposed to the first heat transfer section in a region where the sheet passes.
