摘要：
An inkjet printing apparatus which can perform cost-down and an improvement on a print quality by simplification of an apparatus construction is realized. For realizing such an apparatus, a gas-liquid separation is achieved by the construction where air bubbles generated in an ejection portion or a reservoir can rise to a liquid surface, and a negative pressure control and at the same time, discharge of the air bubbles are performed by a fan.
