摘要： An image forming apparatus includes a plurality of nozzles to discharge liquid droplets; a recording head including a pressure generator to generate a pressure to cause the nozzles to discharge liquid droplets; a droplet discharge status sensor unit to detect a droplet discharging status from each nozzle; and a maintenance controller to control a maintenance operation by a dummy discharge of liquid droplets not contributing to image formation. In such an image forming apparatus, the droplet discharge status sensor unit compares a detection result of the droplet discharge status and a preset reference threshold and determines whether the nozzle discharges normally or defectively; and the maintenance controller outputs a dummy discharge drive waveform corresponding to a difference between the detected droplet discharge status and the reference threshold to the pressure generator of the nozzle determined to be defective to cause the nozzle to discharge droplets for dummy discharging.
