Original Abstract Submitted
in a liquid ejection apparatus, density unevenness of initial ejection from ejection openings after ejection stop can be reduced in a region in which printing is performed by relative movement of an ejection head. the liquid ejection apparatus includes: an ejection head including ejection openings, pressure chambers communicating with the ejection openings, and a flow path communicating with each pressure chamber; a generation mechanism configured to generate liquid flow passing through each pressure chamber via the flow path and differentiate first and second directions of liquid flow for each ejection opening; a scanning mechanism configured to scan the ejection head in the first and second directions; and a control unit configured to perform printing by causing the scanning mechanism to scan the ejection head relative to a printing medium and ejecting liquid from the ejection openings of the first and second directions to a unit region.
