1. An ejection apparatus comprising:
an ejection head including a plurality of ejection ports and configured to eject a droplet from each of the plurality of ejection ports formed on an ejection port surface;
a droplet detection unit configured to detect that the ejected droplet has reached a predetermined position;
a change unit configured to change a distance between the ejection port surface of the ejection head and the droplet detection unit; and
a determination unit configured to determine an ejection timing of the droplet of when an image is printed on a recording medium by the ejection head, by detecting the droplet ejected from each of the plurality of ejection ports by the droplet detection unit when the distance from the ejection port surface of the ejection head to the predetermined position is a first distance and detecting the droplet ejected from each of the plurality of ejection ports by the droplet detection unit when the distance from the ejection port surface of the ejection head to the predetermined position is a second distance,
wherein the ejection head prints, in accordance with the timing determined by the determination unit by detecting the droplet by the droplet detection unit, a pattern for adjusting the ejection timing on the recording medium at a timing that is after the determination performed by the determination unit by detecting the droplet by the droplet detecting unit, and
wherein the determination unit determines the ejection timing, based on the pattern and a result of the droplet detection by the droplet detection unit.
