An ink jet recording apparatus which performs recording using a plurality of types of inks which are different in nature such as level of thickness, improved to attain excellent gradation of recorded image with a reduced number of ink types which are prepared beforehand. In one form, a clear ink which does not contain any dye is mixed with an ink which contains dye so as to form an ink blend of a density which can be set by varying the mixing ratio. The ink blend thus formed is supplied to a recording head. The invention also provides an ink jet recording apparatus which permits inks of different compositions to be blended within the recording apparatus so a to enable selection of ink composition which is optimum for the image to be recorded or purpose of use.

A liquid container for a liquid jet recording apparatus comprises a first chamber containing negative pressure producing material and having a liquid outlet connectable to a liquid jet head to supply liquid from the container to the liquid jet head and an air vent for allowing ambient air into the container, wherein the liquid outlet is provided in a bottom portion of the first chamber. A second chamber communicates with the first chamber by a communication path and is substantially hermetically sealed. A wall extends upwardly from the communication path of the first chamber. An ambient air introducing path is provided for between the wall and the negative pressure producing material extending from a point partly up the wall toward the communication path for introducing ambient air into the second chamber.

A Liquid ejecting method for ejecting liquid using a bubble, includes using a liquid ejecting head having an ejection outlet for ejecting the liquid, a bubble generating region where a bubble is generated in the liquid, a movable member which is disposed faced to the bubble generating region, and which is displaceable between a first position and a second position farther from the bubble generating region than the first position and which has a free end at a downstream side thereof; displacing the movable member from the first position to the second position by pressure based on generation of the bubble in the bubble generating region, wherein the bubble expands more to the downstream side than to the upstream side with respect to a direction toward the ejection outlet by the displacement of the movable member, thus directing the bubble toward the ejection outlet to eject the liquid through the ejection outlet; and imparting an operation to the liquid ejecting head to normalize a state of the liquid in a liquid flow path for the liquid at least before liquid ejection start or at the time of non-ejection of the liquid.

An ink jet cartridge comprises an ink jet head unit for discharging the ink, and an ink tank unit having an ink supply port for supplying the ink to the ink jet head unit. The ink tank unit has a partition portion for partitioning between an ink storing portion for storing the ink to be supplied to the ink jet head unit and a negative pressure generating member receiving portion having a negative pressure generating member. The ink supply port is provided on the negative pressure generating member receiving portion. The partition portion has an ink communicating portion at an end portion of the partitioning portion on the side of the negative pressure generating member receiving portion where the ink supply port is provided, and makes contiguous the ink storing portion and the negative pressure generating member receiving portion in a movement direction of the ink tank unit when discharging the ink.
