Abstract: A nozzle plate includes a nozzle open to one surface of the nozzle plate to eject ink, and a diamond-like carbon (DLC) layer disposed adjacent to the one surface. The DLC layer has surface irregularities including recesses and protrusions. The protrusions adjoining one another have ends to be in contact with the ink. The ends are located at mutually different positions in a direction intersecting the one surface.

Abstract: A nozzle plate includes a nozzle from which a liquid is ejected and that has an opening at one surface side of the nozzle plate and a liquid repelling layer containing a cross-linked fluororesin and formed on the one surface side of the nozzle plate.

Abstract: A wiping member is configured to wipe a nozzle forming surface of a liquid ejecting head, which has nozzles through which a liquid is ejected, in a first direction. The wiping member includes a fibrous material and is configured to satisfy the following: ?a+3?a??f+3?f where ?f is an average of sizes of spaces between fibers in the first direction, ?f is a standard deviation of the sizes of the spaces, ?a is an average of sizes of aggregation substances formed of a solute in the liquid adhered to the nozzle forming surface in the first direction, and ?a is a standard deviation of the sizes of the aggregation substances.

Abstract: An ink jet printer includes a transport mechanism that transports a medium in a first direction; and a carriage that includes a plasma irradiation mechanism, which emits plasma generated in a discharge portion from a plasma irradiation port and then irradiates at least a part of the medium with the plasma, and a head which ejects ink onto the part of the medium which is irradiated with the plasma, and that moves in a second direction intersecting with the first direction, in which the plasma irradiation mechanism is provided on one side of the head in the second direction, and the discharge portion of the plasma irradiation mechanism is disposed so as not to come in contact with the medium.

Abstract: An ink jet printer includes a transportation mechanism that transports a medium in a first direction; a plasma irradiation mechanism that irradiates the medium with plasma; a head mechanism that ejects ink to a portion of the medium irradiated with the plasma and moves in a second direction intersecting the first direction; and a control section that controls whether to irradiate the medium with the plasma by the plasma irradiation mechanism, wherein the control section prohibits the irradiation of the medium with the plasma when a transportation speed of the medium is in a range of 0 m/min to 0.1 m/min, and irradiates the medium with the plasma when the transportation speed of the medium is greater than 0.1 m/min.

Abstract: An ink jet printer including a transportation mechanism transporting a medium in a first direction; and a carriage having a plasma irradiation mechanism that irradiates a portion of the medium with plasma generated in an electricity discharge portion and emitted from a plasma irradiation opening and a head that ejects ink from a nozzle to the plasma irradiated portion of the medium, and that moves in a second direction intersecting the first direction. The plasma irradiation mechanism is on one side of the head in the second direction, a partition board is between the plasma irradiation opening and the head, and if a distance from the medium's surface to the nozzle is (A), a distance from the medium's surface to the plasma irradiation opening is (B), and a distance from the medium's surface to the bottom edge of the partition board is (C), then (C)<(A)?(B).
