Abstract: To prevent, in a configuration to bring a heat sink into contact with a belt to cool the belt, wear of the belt caused by the heat sink when preventing close adhesion between the heat sink and the belt.SOLUTION: A heat absorption part 30a of a heat sink 30 is divided into a first surface 31 and a second surface 32, and a step part 33 is provided from the first surface 31 toward the second surface 32 to be separated from a first belt 21. The step part 33 divides the second surface 32 into a contact area 32a in contact with an inner peripheral surface of the first belt 21 and a non-contact area 32b not in contact with the inner peripheral surface of the first belt 21. The non-contact area 32b forms a gap 70 that allows air to pass in a width direction in the heat absorption part 30a. During the rotation of the first belt 21, air passes through the gap 70 formed by the step part 33 to achieve contact of the inner peripheral surface of the first belt 21 with outer air, and thereby making it difficult for the first belt 21 and the heat absorption part 30a to closely adhere to each other. When the step part 33 is provided, the heat absorption part 30a does not have an edge corner part, and wear of the first belt 21 can thus be prevented.SELECTED DRAWING: Figure 3
