Liquid ejection apparatus

A liquid ejection apparatus comprising:

• a conveyance mechanism which conveys recording media in a conveyance direction;
• a liquid ejection head having an ejection surface on which a plurality of ejection openings ejecting droplets are aligned in a direction orthogonal to the conveyance direction and a plurality of actuators which generate an ejection energy causing the droplets to be ejected through the ejection openings;
• a determining unit which determines, in the ejection surface, an ejection region which opposes, when the recording media are being conveyed, a recording region where an image is recorded on a reference recording medium which is at least one of the recording media successively conveyed by the conveyance mechanism and a non-ejection region which does not oppose the recording region when the recording media are being conveyed;
• and
• a recovery action control unit which controls the actuators such that, both in the ejection openings in the ejection region and in the ejection openings in the non-ejection region, at least one of preliminary ejection with which the droplets are ejected through the ejection openings and preliminary vibration with which meniscus of liquid at each of the ejection openings is vibrated without allowing the ejection openings to eject the droplets is carried out in a recovery period in which none of the ejection openings opposes a recording region on each of the recording media on which region an image is recorded, wherein,
• the recovery action control unit controls the actuators such that an ejection amount of the liquid regarding the preliminary ejection in the recovery period is larger in the ejection openings in the ejection region than in the ejection openings in the non-ejection region and a frequency of vibration of the meniscus regarding the preliminary vibration in the recovery period is higher in the ejection openings in the ejection region than in the ejection openings in the non-ejection region.
