Abstract

Provided is an ink jet recording method capable of recording a high-quality image in which a shift in color tone of a secondary color image recorded with a plurality of inks through use of a circulation serial head is reduced. The ink jet recording method includes recording an image by ejecting an ink from a recording head including: a plurality of ejection orifices; an ejection element; and a first flow path and a second flow path which communicate to each other between each of the plurality of ejection orifices and the ejection element and inside which the ink flows. The plurality of ejection orifice arrays includes a first ejection orifice array to eject a first ink and a second ejection orifice array to eject a second ink. A molar fraction Rof water in the first ink and a molar fraction Rof water in the second ink satisfy R<R.
