Abstract: A water-based ink for ink-jet recording includes a coloring agent, water, and a water-soluble organic solvent. In the water-based ink after drying, a phase (?) obtained by a tan ? measured at about 25° C. is constantly about 45 degrees or more. In other words, the phase (?) never becomes less than about 45 degrees at a strain amount of about 0.1% to about 100%.

Abstract: An ink-jet recording apparatus includes: an ink-jet head including a plurality of nozzle openings from which ink is ejected and an ink ejection surface in which the plurality of nozzle openings are formed; a waste-ink receiving mechanism which receives the ink ejected from the plurality of nozzle openings; a set of (a) a wiper configured to wipe the ink adhering to the ink ejection surface and (b) an absorbing member configured to absorb the ink received by the waste-ink receiving mechanism and to be brought into contact with the ink ejection surface such that the absorbing member adheres the ink thereto; and a driving mechanism configured to drive at least one of the ink-jet head and the set of the wiper and the absorbing member, such that the wiper and the absorbing member are, one of together and independently, moved relative to the ink ejection surface while being opposed thereto, and such that the absorbing member adheres the ink to the ink ejection surface and the wiper wipes the ink adhered by the abso

Abstract: A water-based ink for ink-jet recording includes a coloring agent, water, and a water-soluble organic solvent. In the water-based ink after drying, a tan ? at a frequency of about 100 (1/sec) measured at about 25° C. represented by the following Equation (1) is about 4 or more tan ?=G?/G???(1) tan ?: loss tangent G?: storage elastic modulus G?: loss elastic modulus.

Abstract: An inkjet recording apparatus of the present invention includes: a drum which conveys a recording medium, a wiper extended in the axial direction of the drum, and inkjet heads aligned in the circumferential direction of the drum along the outer circumferential surface of the drum. The inkjet heads are moved by a head-moving mechanism to be in a recording position or a wiping position. The wiper-moving mechanism moves the wiper in the circumferential direction along the outer circumferential surface so that the wiper wipes ejection surface of at least one of the inkjet heads while the inkjet heads are in the wiping position.

Abstract: The inkjet recording apparatus includes: a drum which conveys a recording medium, an inkjet head having an ejection surface which faces the outer circumferential surface of the drum, and a cap facing the outer circumferential surface. The inkjet heads are moved by a head-moving mechanism to be in a recording position, wiping position, or a capping position. The cap-moving mechanism moves the cap, in the circumferential direction of the drum along the outer circumferential surface, to: an open position where the cap does not face the ejection surface, or an opposing position in which the cap faces the ejection surface and covers the inkjet head in the capping position.

Abstract: An image recording apparatus of the present invention includes a conveyance mechanism having a circumferential wall. On the circumferential wall are formed suction holes which communicate an internal space inside the circumferential wall with the outside of the circumferential wall. A recording medium is placed on the outer circumferential surface of the circumferential wall, and is conveyed on the outer circumferential surface in a direction of the rotation of the circumferential wall. A suction unit sucks the air in the internal space to create an air flow from the outside of the circumferential wall to the internal space via the suction holes. A recording medium ejection path branches off from the outer circumferential surface at a separating position which is at the most downstream position of a record head or a position further from the supply position S1 than the most downstream position from the supply position.
