Inkjet recording apparatus

An inkjet recording apparatus comprising:

• a recording head that has a plurality of nozzles through which ink is ejected onto a recording medium;
• a tank that stores the ink fed from a container at a predetermined normal liquid level, the tank feeding the ink stored therein to the recording head;
• and
• a circulation flow passage through which the ink circulates from the tank via the recording head to the tank,
• wherein
• the inkjet recording apparatus further comprises:
• a branch flow passage of which one end is connected to a bottom part of the tank and of which another end is connected to a top part of the tank, the branch flow passage being transparent, and
• a connection face between one end of the branch flow passage and the tank is located at a position higher than the normal liquid level but lower than a raised liquid level of the ink to which the ink temporarily rises when the ink returns via the circulation flow passage to the tank.
