摘要
In a sub-tank of an ink jet recording head, an ink absorbing member capable of being impregnated with and holding an ink is arranged and a space V2, which is an area formed by a first wall surface of an ink reservoir and the ink absorbing member and in which the ink absorbing member is not present, is formed. A gas-liquid separation member made of a porous member, transmitting a gas but shutting off a liquid such as the ink is provided in a cap member in which an air hole is formed. A volume of the space V2 and a total volume V2 of an amount of the ink by which the ink is discharged from a discharge port of an ink jet recording element in one recovery operation and an initial pre-discharge amount hold a relationship of 0.7V1≦V2≦V1.
