Liquid ejection apparatus and liquid ejection method

A liquid ejection apparatus comprising:

• a plurality of liquid ejection heads arranged in parallel, each of the liquid ejection heads having an ejection opening from which a liquid is ejected to a medium during relative movement between the liquid ejection head and the medium;
• at least one blowing-out unit communicating with a plurality of blowing-out openings facing the medium so as to blow out gas toward the medium, the plurality of blowing-out openings corresponding to the plurality of the liquid ejection heads and being relatively fixed to the corresponding liquid ejection heads with respect to a movement direction of the medium;
• and
• at least one suction unit communicating with a plurality of suction openings for sucking gas on the medium, the plurality of suction openings corresponding to the plurality of the liquid ejection heads and being relatively fixed to the corresponding liquid ejection heads with respect to the movement direction of the medium,
• wherein each blowing-out opening and each suction opening are provided for each of the corresponding liquid ejection heads,
• wherein each ejection opening, each blowing-out opening, and each suction opening are arranged, regarding each of the corresponding liquid ejection heads, in order from an upstream side to a downstream side in the movement direction of the medium with respect to the liquid ejection head, and
• wherein, regarding each of the corresponding liquid ejection heads, the amount of gas blown out from each blowing-out opening per unit time is larger than the amount of gas sucked into each suction opening per unit time.
