ABSTRACT:
An ink jet recording apparatus is provided with a recording head that ejects ink droplets, an ink tank that supplies ink to the recording head, a waste ink recovering mechanism that recovers ink droplets ejected from the recording head as waste ink, a waste-ink tank, which is connected to the waste-ink recovering mechanism and stores the waste ink, a diluent tank which is communicated with the waste-ink tank and accommodates a diluent that dilutes the waste ink, and at least one of diluent supplier, that is, one of a first diluent supplier which supplies the diluent in the diluent tank to the waste-ink tank to make the conductivity of the waste ink in the waste-ink tank substantially the same as the conductivity of the ink stored in the ink tank and a second diluent supplier which supplies the diluent in the diluent tank to the waste-ink tank to make the specific gravity of the waste ink in the waste-ink tank substantially the same as the specific gravity of the ink stored in the ink tank. Further, an ink jet recording method uses this ink jet recording apparatus.
