An ink jet recording method for performing a recording operation comprising the steps of:
- discharging an ink droplet composed of ink containing a pigment, a water soluble resin for dispersing said pigment and water to a recording member, on which data is recorded;
- and
- supplying a solution containing at least one of particles and binder polymer on to said recording member prior to discharging said ink, wherein said solution reduces dispersion stability of said ink to generate aggregation of said ink.
An ink jet recording method for performing a recording operation comprising the steps of:
- discharging an ink droplet composed of an ink composition containing a pigment, a first polymer having a polarity for dispersing said pigment and water to a recording member, on which data is recorded;
- and
- supplying a solution containing a second polymer that has a polarity opposite the polarity of said first polymer contained in said ink composition, on to said recording member prior to discharging said ink, wherein said solution reduces dispersion stability of said ink to generate aggregation of said ink.
An ink jet recording method for performing a recording operation comprising the steps of:
