Abstract
To provide an ink jet recording method using facedown discharge and capable of obtaining a recorded matter being suppressed a generation of minus curl. The method provided is an ink jet recording method including a step of recording an image on a recording medium having a first surface and a second surface by ejecting an aqueous ink from a recording head. This method further includes, after the recording step, a step of discharging the recording medium while placing the first surface or the second surface on which the image has been recorded last on a gravitationally lower side. In this method, the aqueous ink has a viscosity ηof 5.0 mPa·s or more and a difference η−ηbetween a viscosity ηof an evaporated ink obtained by evaporating 20% by mass of the aqueous ink and the viscosity ηof the aqueous ink is 4.0 mPa·s or more.
