RECORDING APPARATUS AND RECORDING METHOD

The invention relates to a recording apparatus and method. The recording apparatus includes an ejecting head that ejects aqueous ink which includes a colorant, polymer particles, water, and an aqueous organic solvent, of which static surface tension is from 22 mN/m to 30 mN/m, and a difference betwe...

More Information
Summary:The invention relates to a recording apparatus and method. The recording apparatus includes an ejecting head that ejects aqueous ink which includes a colorant, polymer particles, water, and an aqueous organic solvent, of which static surface tension is from 22 mN/m to 30 mN/m, and a difference between a value of dynamic surface tension after 10 msec and a value of dynamic surface tension after 1000 msec is greater than 2 mN/m and equal to or smaller than 10 mN/m, when dynamic surface tension is measured with a maximum bubble pressure technique, in an the ink droplet amount in a range of less than 10 pl. Stripe-like or irregular image defect can be suppressed by adopting the recording apparatus of the invention.
