Abstract
To provide an ink jet recording method excellent in a fixability of an image, capable of recording an image excellent in optical density, and excellent in a recoverability, when it uses a recording apparatus having a line head. This method records an image by using an ink jet recording apparatus equipped with a line head having an ejection nozzle of a pigment-containing aqueous ink and a mechanism for recovering an ejection state of the aqueous ink from the nozzle and applying the ink to a recording medium. The pigment has an average particle diameter of 80 nm or more, the ink has a dynamic surface tension of 55 mN/m or less at a lifetime of 10 milliseconds, the recovery mechanism includes a mechanism for causing the ink in the nozzle to flow, and the viscosity of the ink in the nozzle is reduced.
