ABSTRACT:
A liquid ejection apparatus includes an ejection tank disposed above a conveying path and storing an image-forming solvent, a nozzle plate provided at the ejection tank as a bottom wall of the ejection tank and having a plurality of nozzle holes for ejecting the image-forming solvent, and at least one actuator for moving the nozzle plate reciprocally toward and away from an image-recording material on the conveying path. As the image-forming solvent is ejected from the nozzle holes, bubbles may enter into the ejection tank by way of the nozzle holes. However, the bubbles rise in the ejection tank without remaining in vicinities of the nozzle holes. As a result, a case in which bubbles close the nozzle holes and prevent the image-forming solvent from being released from the nozzle holes is avoided. Consequently, the image-forming solvent can be uniformly applied onto the image-recording material.
