A liquid ejection apparatus includes a liquid ejection head including a plurality of ejection opening groups each constituted by two or more ejection openings and each forming one pixel by at least two liquid droplets ejected from the two or more ejection openings of a corresponding one of the plurality of ejection opening groups; a plurality of individual channels respectively connecting the plurality of ejection opening groups to a plurality of pressure chambers; and an energy-applying portion applying energy to liquid in the plurality of pressure chambers, and a controller controlling the energy-applying portion. The controller controls the energy-applying portion to form one pixel by using at least a first drive signal whose ejection period is a first ejection period and a second drive signal whose ejection period is a second ejection period different from the first ejection period. |
