A nonaqueous ink composition for ink jet recording includes a solvent represented by general formula (1) and having a hydrophile-lipophile balance value of 10.5 to 20.0: where Rdenotes an alkyl group having 1 to 4 carbon atoms.

Nonaqueous ink composition for ink jet recording and ink jet recording method

A recording apparatus includes a head, wherein a manifold in which an ink flows, and a plurality of ink flow paths divided from the manifold and arranged in a first direction are formed in the head; a nozzle opening portion discharging the ink flowing from the manifold is formed in the ink flow path; when a maximum area is Cand a minimum area is Cin a cross section of the ink flow path including the first direction and a vertical direction, except a cross section including the nozzle opening portion, the Cis more than once and equal to or less than 3.5 times the C; and the ink contains a flaky pigment having an average thickness of 5 nm or more and 50 nm or less and a 50% average particle diameter of an equivalent circle diameter of 0.5 &#x3bc;m or more and 2.1 &#x3bc;m or less.

Ink jet recording apparatus and recorded matter

An ink composition for ink jet textile printing at least includes a disperse dye and a solvent represented by the following Formula (1): (in Formula (1), Rdenotes an alkyl group having 1 to 4 carbon atoms). The solvent represented by the Formula (1) has an HLB value of 10.5 or more and 20.0 or less.

A liquid ejecting apparatus has a head component that ejects a liquid through nozzle openings to attach the liquid to an object. The liquid contains a tabular grain material, and the head component discharges the liquid in droplets weighing 1 ng to 7 ng, both inclusive, in a way that the droplets reach the object at a velocity of 5 m/s to 8 m/s, both inclusive.

Liquid ejecting apparatus

A liquid ejecting head including: a head main body that has a nozzle opening for ejecting liquid, a rectifying plate that is disposed in a position away from the liquid ejecting surface on which the nozzle opening is opened and has an opening disposed in an area facing the nozzle opening, and an air stream generating unit that generates an air stream between the liquid ejecting surface and the rectifying plate along the surface direction of the liquid ejecting surface.
