<p>PROBLEM TO BE SOLVED: To provide a roller, a cylinder and a printer which are used for cooling a high temperature state to an appropriate temperature, and which can improve cooling efficiency by using a thermoelectric transducer.SOLUTION: A roller includes: a roller exterior cylinder 5 for forming an exterior of the roller; a plurality of thermoelectric transducers; a case 300 (configured so as to sandwich the plurality of thermoelectric transducers by a mounting plate 8, a heat radiation member 9 and a curved plate 10) for receiving the plurality of thermoelectric transducers; and a support body 301 for bringing the case 300 into contact with an inner wall of the roller exterior cylinder 5. The support body 301 comprises: a unit movable plate 13 for holding the case 300; and a support part 7 for supporting the unit movable plate 13 in a movable manner via a screw with a spring 11. The screw with a spring 11 moves the unit movable plate 13 toward the inner wall of the roller exterior cylinder 5.</p> |
