Inkjet recording apparatus

An inkjet recording apparatus, comprising:

• a recording head including a plurality of nozzles for ejecting ink;
• an endless conveyance belt that has a plurality of openings for the ink ejected from the recording head to pass through and conveys a recording medium;
• a control portion that controls driving of the recording head and the conveyance belt so as to execute flushing in which, at a timing different from a timing contributing to image recording, the ink is ejected through the nozzles of the recording head to pass through any of the plurality of openings;
• an ink collector that is disposed to be opposed to the recording head via the conveyance belt and collects the ink that has passed through the openings during execution of the flushing;
• and
• a suction portion that sucks air in the ink collector,
• wherein
• the ink collector includes:
• a plurality of ink receivers that receives the ink that has passed through the openings;
• a waste ink tank disposed below the ink receivers;
• a suction path that is formed in the waste ink tank and leads from each of the ink receivers to the suction portion;
• and
• an ink absorber that is filled in the waste ink tank and absorbs the ink sucked from the ink receivers, and
• the suction path is formed by void spaces surrounded by the ink absorber, wherein
• the ink absorber is composed of a plurality of block-shaped ink absorbing members, and
• the suction path is formed by stacking the plurality of block-shaped ink absorbing members.
