Abstract
An ink jet recording method includes a treatment liquid attachment step, in which a treatment liquid containing a flocculant is attached to a recording medium, and an ink attachment step, in which an ink composition containing a pigment and resin particles is attached to the recording medium by ejecting the ink composition from an ink jet head. When the ink composition is mixed in a 1:1 ratio by mass with a 6% by mass aqueous solution of magnesium sulfate heptahydrate, the volume-average diameter of particles in the mixture is from 2000 to 6000 nm.
