<P>PROBLEM TO BE SOLVED: To provide an ink jet recording method exhibiting excellent character quality, strike through resistance, curl resistance, continuous ejection properties and intermittent ejection properties even in printing on a plain paper. <P>SOLUTION: In the ink jet recording method for ejecting an ink drop from a nozzle by expanding/contracting an ink chamber, the ink contains water, a water soluble organic solvent, and a pigment wherein the water soluble organic solvent is 50-90 mass% of all ink, and the water soluble organic solvent having SP value of 16.5-24.6 is 30 mass% or more of all ink. The ink jet recording method comprises a first expansion step, a first contraction step for contracting the ink chamber to eject ink, a second expansion step of larger volume variation than that of the first expansion step, and a second contraction step of smaller volume variation than that of the first contraction step and not ejecting ink. <P>COPYRIGHT: (C)2007,JPO&INPIT |
