Inkjet recording apparatus and image forming method

An inkjet recording apparatus comprising:

• an image forming section including a plurality of nozzles, the image forming section being configured to inject ink from the plurality of nozzles to form an image on a recording medium;
• and
• a controller configured to control the image forming section, wherein
• the controller includes
• a determining section configured to determine whether or not each of the plurality of nozzles is clogged with the ink in a thickened state,
• a changing section configured to change the nozzle to inject the ink, from a first nozzle to a second nozzle, based on a determination result of the determining section, and
• a generating section configured to generate image data based on the determination result of the determining section,
• the controller controls the image forming section to inject the ink from the second nozzle to form an image on the recording medium based on the image data,
• the first nozzle is clogged with the ink in the thickened state, and
• the second nozzle is different from the first nozzle.
