摘要： The object is to prevent high-viscosity liquid and air bubbles generated in a damper chamber from flowing into the ejection module. A printer 1 includes: ejection modules 21-26; supply chambers 33 connected to the ejection modules 21-26 and to respective sub-tanks 12 each storing ink; and damper chambers 34 connected to the respective supply chambers 33. Each of the supply chambers 33 has: openings 41, 42 communicating with a corresponding one of the damper chambers 34; and an opening 43 communicating with a corresponding one of the sub-tanks 12. That is, this printer 1 is not configured such that the damper chamber 34 is disposed between the sub-tank 12 and the supply chamber 33. Accordingly, even in case where increase in viscosity of ink and/or generation of air bubbles occurs in the damper chamber 34, it is possible to make it more diffcult for the high-viscosity ink and/or the air bubbles to flow into the ejection modules 21-26 during ink ejection from the ejection modules 21-26.
