1. An inkjet recording apparatus comprising:
a conveying belt including a plurality of openings and capable of sequentially conveying recording media;
a recording head including a plurality of nozzles that eject ink onto the recording medium being conveyed by the conveying belt to form an image on the recording medium; and
a flushing controller that allows the recording head to do flushing by allowing each of the nozzles of the recording head to eject the ink with a different timing from a timing to form the image and allowing the ink ejected from the nozzle to pass through any one of the plurality of openings,
wherein the conveying belt includes the openings formed as a plurality of rows of openings, each row composed of openings arranged at predetermined intervals in a widthwise direction of the conveying belt,
the plurality of rows of openings are arranged at predetermined intervals in a direction of conveyance of the conveying belt so that the openings of each of the plurality of rows of openings include overlapped portions at which the openings are overlapped with the openings of any other of the plurality of rows of openings along the widthwise direction of the conveying belt, and
the flushing controller allows the recording head to do the flushing by allowing each of all the nozzles inclusive of the nozzles facing the overlapped portions to eject the ink a predetermined number of times in an image non-formation period during which travel of the conveying belt causes the openings to pass through a location facing the recording head,
the inkjet recording apparatus further comprising a display that displays a notification about execution of the flushing,
wherein when the number of ejections of the ink from any of the nozzles in the image non-formation period has not reached the predetermined number, the flushing controller allows the display to display a notification that the flushing is insufficient, and
wherein when the number of ejections of the ink from all the nozzles in the image non-formation period has reached the predetermined number, the flushing controller not allows the display to display the notification that the flushing is insufficient.
