An inkjet printer for recording dot patterns corresponding to image contents is disclosed. The printer comprises an inkjet head (51) for performing recording by moving in a main scanning direction of a recording medium and injecting ink particles, drive waveform generating sections (24, 25) for generating drive waveforms for injecting said ink particles, and a head drive section (50) for selecting said drive waveforms and driving said inkjet head (51) in accordance with print data. The drive waveform generating sections (24, 25) generate drive waveforms for injecting said ink particles having different ink speeds within a unit cycle, in cycles each corresponding to one of the parts obtained by dividing the unit cycle by an integer. Thereby, by varying the speed of the ink particles injected in one cycle of the drive waveforms, the landing position of each dot in the cycle is controlled and hence the dot pattern in one cycle is varied. Since this is achieved by means of the drive waveforms, it can be implemented without changing the image data.
