Liquid ejection method for ejecting an ink containing a color material and an improvement liquid

A liquid ejection head comprising:

• a first ejection port configured to eject an ink containing a color material;
• a first energy generating element configured to generate energy utilized for ejecting an ink from the first ejection port;
• a second ejection port configured to eject an improvement liquid for improving recording property of the ink;
• a second energy generating element configured to generate energy utilized for ejecting the improvement liquid from the second ejection port;
• and
• a third energy generating element which corresponds to the second ejection port in addition to the second energy generating element and is configured to control a position of the liquid level of the improvement liquid,
• wherein the improvement liquid is ejected from the second ejection port by driving the second energy generating element in a state where a liquid level of the improvement liquid in the second ejection port has moved forward in a liquid ejection direction than a liquid level of the ink in the first ejection port when the first energy generating element is driven.

A liquid ejection apparatus comprising:

• a liquid ejection head which includes a first ejection port configured to eject an ink containing a color material, a first energy generating element configured to generate energy utilized for ejecting the ink from the first ejection port, a second ejection port configured to eject an improvement liquid for improving recording property of the ink, and a second energy generating element configured to generate energy utilized for ejecting the improvement liquid from the second ejection port;
• and
• a unit configured to generate a difference between a position of a liquid level of the ink in the first ejection port when the first energy generating element is driven and a position of a liquid level of the improvement liquid in the second ejection port when the second energy generating element is driven,
• wherein the improvement liquid is ejected from the second ejection port by driving the second energy generating element in a state where the liquid level of the improvement liquid in the second ejection port has moved forward in a liquid ejection direction by the unit than the liquid level of the ink in the first ejection port when the first energy generating element is driven.

A method for ejecting a liquid using a liquid ejection head,

• wherein the liquid ejection head includes a first liquid ejection head configured to eject a main droplet of a first liquid and a plurality of minute liquid droplets accompanying the main droplet, and a second liquid ejection head configured to eject a main droplet of a second liquid and a plurality of minute liquid droplets accompanying the main droplet, and
• a number of the minute liquid droplets ejected from the second liquid ejection head is smaller than a number of the minute liquid droplets ejected from the first liquid ejection head, the method comprising the steps of:
• ejecting an ink containing a color material from the first liquid ejection head;
• and
• ejecting an improvement liquid for improving recording property of the ink from the second liquid ejection head.
