Abstract
An ink jet recording method uses an apparatus including plural aqueous inks including cyan, magenta and yellow inks; a recording head that thermally ejects the inks; a first ink storage portion having an atmosphere communicating portion; a second ink storage portion which is a resinous housing and is directly bonded to the head; and a tube that supplies the inks from the first to second ink storage portions and includes first, second and third tubes corresponding to the respective inks, the second tube having a portion sandwiched between and joined to the first and third tubes. The method includes ejecting the inks from the head to record an image on a recording medium. The difference between the maximum and minimum values of water molar fractions of the cyan, magenta and yellow inks is 5.0% or less. The tube corresponding to the magenta ink is the second tube.
