INK JET RECORDING METHOD
First Claim
1. An ink jet recording method, comprising:
- an ink application step, that is, a step of ejecting an aqueous ink containing a resin particle from a line head to apply the aqueous ink to a predetermined position of a recording medium having ink absorbability, anda fixing step, that is, a step of bringing a heating roller into contact with the aqueous ink applied to the recording medium to heat the aqueous ink and fixing it to the predetermined position;
wherein a dynamic surface tension γ
I (mN/m) of the aqueous ink when the heating roller is brought into contact therewith is higher than a surface tension γ
R (mN/m) of the heating roller.

Abstract
To provide an ink jet recording method capable of recording a high-quality image excellent in optical density and water resistance and at the same time, suppressing peeling-off of an image caused by contact heating of a recording medium. The ink jet recording method has a step of ejecting an aqueous ink containing a resin particle from a line head and applying the aqueous ink to a predetermined position of a recording medium having ink absorbability and a step of bringing a heating roller into contact with the aqueous ink applied to the recording medium to heat it and fixing it at the predetermined position. The dynamic surface tension of the aqueous ink at the time when the heating roller is brought into contact with the aqueous ink applied to the recording medium is higher than the surface tension of the heating roller.
