## Abstract

A heating device includes a heating unit that heats a member to be heated, which is transported, as a result of a contact portion of the heating unit being in contact with the member to be heated, a heat pipe that contacts with a portion of the heating unit different from the contact portion in such a manner as to extend in a widthwise direction crossing a transport direction of the member to be heated and that includes a crimped portion formed at a first end of the heat pipe, and a power-supply connection unit that is disposed on a second end side of the heat pipe and that is connected to a wiring line through which power is supplied to the heating unit.

## Claims

### Claim 1

A heating device comprising:
a heating unit that is configured to heat a member to be heated, which is transported, as a result of a contact portion of the heating unit being in contact with the member to be heated;
a heat pipe that contacts with a portion of the heating unit different from the contact portion in such a manner as to extend in a widthwise direction crossing a transport direction of the member to be heated and that includes a crimped portion formed at a first end of the heat pipe; and
a power-supply connection unit that is disposed on a second 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 heat pipe is in contact with the heating unit via a thermally conductive adhesive.

### Claim 2 (depends on 1)

The heating device according to claim 1,
wherein the crimped portion is provided with a hygroscopic member disposed in such a manner as to be in contact with or close to the crimped portion.

### Claim 3 (depends on 2)

The heating device according to claim 2,
wherein the heating unit heats the member to be heated that is transported from a lower side to an upper side in such a manner as to pass through the heating unit, and
wherein the power-supply connection unit is disposed at a position that corresponds to an end of the heating unit, the end being located on the upper side.

### Claim 4 (depends on 1)

The heating device according to claim 1,
wherein the heating unit heats the member to be heated that is transported from a lower side to an upper side in such a manner as to pass through the heating unit, and
wherein the power-supply connection unit is disposed at a position that corresponds to an end of the heating unit, the end being located on the upper side.

### Claim 5 (depends on 1)

An apparatus using a member to be heated comprising:
a transport unit that transports a member to be heated; and
a heating device that heats the member to be heated, which is transported by the transport unit,
wherein the heating device is formed of the heating device according to claim 1.

### Claim 6

A heating device comprising:
heating means for heating a member to be heated, which is transported, as a result of a contact portion of the heating means being in contact with the member to be heated;
a heat pipe contacting with a portion of the heating means different from the contact portion in such a manner as to extend in a widthwise direction crossing a transport direction of the member to be heated, the heat pipe including a crimped portion formed at a first end of the heat pipe; and
a power-supply connection unit disposed on a second end side of the heat pipe, and connected to a wiring line through which power is supplied to the heating means,
wherein the heat pipe is in contact with the heating means via a thermally conductive adhesive.
