ABSTRACT:
Provided is an ink-jet head and an ink-jet type recording apparatus for improving an impact position accuracy of ink droplets by eliminating a discharge speed difference of ink droplets when an ink volume is changed gradually in a plurality of steps to perform gradation expression. Among discharge pulse signals to be applied a plurality of times for gradually changing and discharging the ink droplet volume, a signal waveform of a final drive pulse and a signal waveform of an initial drive pulse to be operated at least once before the final drive pulse, are varied from each other so as to establish a predetermined relation therebetween.
