1. A heating device comprising:
a heating unit comprising a contact portion having a first surface, configured to heat a member to be heated having a second surface, which is transported, as a result of the contact portion of the heating unit being in contact with the member to be heated;
a heat pipe that is configured to have a first end and a second end opposite to the first end in a widthwise direction, and contact with a portion of the heating unit different from the contact portion in such a manner as to extend in the widthwise direction crossing a transport direction of the member to be heated, wherein the heat pipe includes a crimped portion only disposed at a first end side of the heat pipe;
a rotating body comprising a third surface, configured to rotate in such a manner as to press the member to be heated;
a power input unit, comprising a gear, that is only disposed on a second end side of the heat pipe and that configured to input a rotational force at least to the rotating body; and
a power-supply connection unit that is disposed on the first end side of the heat pipe and that is connected to a wiring line through which power is supplied to the heating unit,
wherein the crimped portion is located on the first end side opposite to the second end side on which the gear is disposed,
