LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS

A liquid ejection head is capable of ejecting a liquid (I) through an ejection port (20A), the liquid (I) being supplied from a liquid container (30) with a negative pressure generating section (31, 33-1, 33-2), the liquid ejection head (20) comprising: a liquid chamber (21) configured to contain th...

Zusammenfassung:	A liquid ejection head is capable of ejecting a liquid (I) through an ejection port (20A), the liquid (I) being supplied from a liquid container (30) with a negative pressure generating section (31, 33-1, 33-2), the liquid ejection head (20) comprising: a liquid chamber (21) configured to contain the liquid (I); a liquid supply section (22) configured to allow the liquid (I) to be supplied from the liquid container (30) to the liquid chamber (21); an opening (25) configured to communicate with the liquid chamber (21) and to enable at least a gas to flow into the liquid chamber (21) through the opening (25); and a filter member (23) provided in the liquid supply section (22) and configured to form a meniscus of the liquid (I), the meniscus of the liquid (I) formed in the filter member (23) is larger, in meniscus force applied to the liquid (I), than a meniscus of the liquid (I) formed in the ejection port (20A).
