INKJET INK
An inkjet ink includes a self-dispersing pigment, specific particles and an aqueous medium. The specific particles include a pigment and a resin. In the specific particles, the mass ratio of the resin to the pigment is equal to or greater than 1.2 and equal to or less than 2.0. The resin includes a styrene-(meth)acrylic resin. The volume median diameter of the specific particles is equal to or greater than 100 nm and equal to or less than 170 nm.
INKJET RECORDING APPARATUS
An inkjet recording apparatus includes two or more line recording heads and inks each accommodated in a corresponding one of the line recording heads. The line recording heads perform ink ejection onto a recording medium in a specific order at a regular ejection interval T. The ejection interval T is at least 300 milliseconds and no greater than 530 milliseconds. The line recording heads include at least a first line recording head that performs ink ejection onto the recording medium first and a second line recording medium that performs ink ejection onto the recording medium next to the first line recording head. Each of the inks contains a pigment, a water-soluble organic solvent, and water. The water-soluble organic solvent includes a glycol ether compound.

INKJET INK AND INKJET RECORDING METHOD
An inkjet ink contains a pigment, a water-soluble organic solvent, water, and a surfactant. The water-soluble organic solvent includes a glycol ether compound. A difference between a dynamic surface tension ?.sub.10 of the inkjet ink at a surface age of 10 milliseconds and a dynamic surface tension ?.sub.10000 of the inkjet ink at a surface age of 10000 milliseconds is no greater than 3.4 mN/m. An inkjet recording method is an inkjet recording method for forming an image on a recording medium with the above-mentioned inkjet ink and includes forming the image by ejecting the inkjet ink toward the recording medium. The recording medium is a poorly absorbent recording medium.
