Abstract
A drive apparatus for a liquid ejection head, includes a drive signal generating device for generating a drive signal to operate an ejection energy generating element provided so as to correspond to a nozzle of the liquid ejection head, the drive signal being supplied to the ejection energy generating element so that a liquid droplet is caused to be ejected from the nozzle, wherein: the drive signal includes a plurality of ejection pulses for performing a plurality of ejection operations during one recording period, in a remaining pulse sequence excluding a final pulse of the plurality of ejection pulses, a voltage amplitude of a subsequent pulse is smaller than a voltage amplitude of a preceding pulse, and the final pulse has a largest voltage amplitude, of the plurality of ejection pulses.
