The influence of variations in ejection characteristics of nozzles in an ejection head is more appropriately suppressed. A liquid ejection apparatus that ejects liquid droplets comprises: an ink jet head 12 representing an ejection head having a plurality of nozzles 102 and a plurality of driving elements 104; a driving signal output unit 18; an ejection nozzle setting unit 20; and a timing setting unit 22 that sets a timing at which the driving elements 104 receive a driving signal, wherein the driving signal output unit 18 outputs a voltage change signal representing a signal, in which a voltage changes with time, to the plurality of nozzles 102 in common as at least a part of the driving signal, the timing setting unit 22 separately sets a period, in which the driving elements 104 receive the voltage change signal, for each of the driving elements 104, and each of the nozzles ejects the liquid droplets in an ink jet system according to the driving signal in which the period for receiving the voltage change signal is separately set. |
