Claim Text:
1. An ink jet recording method of recording an image by using at least a first ink composition containing water, a surfactant, and a first coloring material and a second ink composition containing a second coloring material different from the first coloring material on a recording medium, the method comprising: recording an image on the recording medium by causing a first recording head that ejects the first ink composition and a second recording head that ejects the second ink composition to eject the first ink composition and the second ink composition while relative positions thereof with respect to the recording medium are changed, wherein, in the recording of the image, a time after the first ink composition is ejected to a predetermined area of the recording medium and before the second ink composition is ejected to the predetermined area is in the range of 10 ms to 2,000 ms, wherein a viscosity of the ink composition at 20° C. when the first ink composition is ejected is 15 mPa·s or less, and wherein the viscosity at 20° C. when 50% of a volatile component contained in the first ink composition is volatilized is 100 mPa·s or greater.
