To provide a temperature adjustment device which can quickly cool a heated recording head while suppressing excessive cooling of the recording head.SOLUTION: A temperature adjustment device 25 comprises: a recording head 14 which discharges droplets from a plurality of nozzles toward a sheet S; a cooling part 32 which releases heat of cooling liquid that has cooled the recording head 14 by a heat release part 34 while making the cooling liquid circulate along a cooling flow channel 35; a bypass flow channel 37 which makes the cooling flow channel 35 heading toward the recording head 14 from the heat release part 34 communicate to the cooling flow channel 35 heading toward the heat release part 34 from the recording head 14 by bypassing the recording head 14; and a switching part 38 which switches opening/closing of the bypass flow channel 37.SELECTED DRAWING: Figure 4 【課題】記録ヘッドの過剰な冷却を抑制しながら加熱された記録ヘッドを迅速に冷却することができる温度調整装置を提供する。【解決手段】温度調整装置２５は、シートＳに向けて複数のノズルから液滴を吐出する記録ヘッド１４と、冷却液を冷却流路３５に沿って循環させながら記録ヘッド１４を冷却した冷却液の熱を放熱部３４で放熱する冷却部３２と、放熱部３４から記録ヘッド１４に向かう冷却流路３５と、記録ヘッド１４から放熱部３４に向かう冷却流路３５とを、記録ヘッド１４を迂回して連通させる迂回流路３７と、迂回流路３７の開閉を切り換える切換部３８と、を備えている。【選択図】図４
