Abstract
An image forming apparatus includes a liquid discharging head unit including multiple nozzles to discharge liquid droplets, individual liquid chambers communicated to the multiple nozzles, and pressure generating units to generate pressure applied to a liquid in the individual liquid chambers; and a head drive control unit to generate a common driving waveform including multiple discharging pulses arranged in time series within one driving cycle of discharging liquid droplets of the liquid, to select at least one of the multiple discharging pulses from the common driving waveform, and to apply the selected at least one of the discharging pulses to the pressure generating units. The common driving waveform, generated by the head drive control unit, include at least a first discharging pulse and a second discharging pulse for discharging liquid droplets of same size.
