Inkjet recording method

1. An inkjet recording method comprising ejecting an ink composition comprising a dispersion medium and charged particles containing at least a colorant by utilizing an electrostatic field, wherein the method comprises preparing as the ink composition, an initial feeding ink composition and a replenishing ink composition in which a volume average particle diameter of the charged particles is controlled larger than a volume average particle diameter of the charged particles in the initial feeding ink composition, and replenishing the replenishing ink composition in order to compensate decrease in concentration of the charged particles due to ejection of the initial feeding ink composition.

2. An inkjet recording method as claimed in claim 1 , wherein the solid content concentration of the replenishing ink composition is controlled higher than the solid content concentration of the initial feeding ink composition.

3. The inkjet recording method as claimed in claim 1 , wherein the volume average particle diameter (DS) of the charged particles of the initial feeding ink composition is adjusted from 0.20 to 4.5 μm, the volume average particle diameter (DR) of the charged particles of the replenishing ink composition is adjusted from 0.21 to 5.0 μm, and a relation between DS and DR is adjusted from 1.05 to 4.0 in terms of a ratio of DR/DS.

4. The inkjet recording method as claimed in claim 3 , wherein the solid content concentration of the initial feeding ink composition is adjusted from 1 to 40% by weight, the solid content concentration of the replenishing ink composition is adjusted from 2 to 60% by weight, and a ratio of the solid content concentration between the initial feeding ink composition and the replenishing ink composition is adjusted from 1.05 to 10.0 in terms of a ratio of the latter/the former.
