Abstract:
1. An image forming apparatus, comprising: large nozzles having large size nozzle openings to eject large droplets of liquid, the large droplets being deposited onto a recording medium and forming large dots; small nozzles having small size nozzle openings of smaller size than the large size nozzle openings so as to eject small droplets of the liquid of volume smaller than the large droplets, the small droplets being deposited onto the recording medium and forming small dots smaller than the large dots; a conversion processing device which converts input image data into ink volume data; a dot information acquisition device which acquires dot information from the dots deposited on the recording medium relating to the large dots and the small dots on the recording medium; and a correction processing device which corrects the ink volume data according to the dot information.
