Patent ID: 11479055

Abstract:
An ink jet recording method includes: a treatment liquid adhesion step of adhering a treatment liquid containing an aggregating agent to a recording medium; an ink adhesion step of adhering an aqueous ink composition containing a colorant to the recording medium by ejection thereof from an ink jet head; a first heating step of heating the recording medium to which the treatment liquid and the aqueous ink composition are adhered to a first surface temperature by a first heating mechanism; a second heating step of heating the recording medium after the first heating step to a second surface temperature which is higher than the first surface temperature by a second heating mechanism provided at downstream than the first heating mechanism in a recording medium transport direction; and a cooling step of, after the first heating step and before the second heating step, cooling the recording medium by a cooling mechanism, and by the cooling step, a surface temperature of the recording medium is decreased to a temperature lower than the first surface temperature.
