1. A liquid ejection device comprising:
a plurality of ejectors configured to eject active energy ray curable liquid;
an active energy ray irradiator configured to emit an active energy ray to the liquid ejected by the plurality of ejectors;
a move control unit configured to move any one of a first element and a second element in a main-scanning direction, and move any one of the first element and the second element in a sub-scanning direction orthogonal to the main-scanning direction, the first element including the plurality of ejectors and the active energy ray irradiator, the second element including an object to which the liquid is ejected; and
a control unit configured to perform control to cause a first ejector of the plurality of ejectors to eject a first ejection amount of liquid, cure the first ejection amount of liquid, cause a second ejector of the plurality of ejectors to eject a second ejection amount of liquid onto the cured first ejection amount of liquid, and cure the second ejection amount of liquid,
wherein
the first ejection amount and the second ejection amount are different from each other, and
the second ejector is different from the first ejector.
