An aqueous inkjet ink of the present disclosure is an active energy ray curable aqueous inkjet ink including a water-soluble monomer having a polymerizable group and a hydrazide compound. The water-soluble monomer is a curable substance having a ketone structure.

Aqueous inkjet ink, aqueous inkjet ink set, and inkjet recording method

Provided is an ink jet printing method including: a first step of ejecting an ink containing a water-soluble polymerizable component A and water from a printing head of an ink jet system to apply the ink to a medium M, to thereby form a first image; and a second step of applying an active energy ray to the first image to form a second image. The polymerizable component A is dissolved in the first image, and a moisture concentration 'x' (mass %) in the first image and a moisture concentration “y” (mass %) in the second image placed under an environment at a humidity of 95% satisfy a relationship of 0<(y/x)≤0.80.

Ink jet printing method, ink jet printing apparatus, method of producing porous body, and apparatus for producing porous body

The active energy ray-curable liquid composition according to the present disclosure is an active energy ray-curable liquid composition that contains water and a curable substance and is curable with an active energy ray, in which the curable substance contains a monofunctional polymerizable monomer having a structure represented by the Formula (1); in Formula (1), R1 represents a hydrogen atom or a saturated hydrocarbon group, R2 represents a saturated hydrocarbon group that has at least one of a hydroxyl group or an amide bond and may contain a heteroatom, R3 represents a hydrogen atom or a methyl group, R1 and R2 may be bonded together to form an aliphatic heterocycle together with a nitrogen atom substituted with R1 and R2 in a case where R1 represents a saturated hydrocarbon group, and a total number of carbon atoms of the saturated hydrocarbon groups represented by R1 and R2 is 5 or more.

Active energy ray-curable liquid composition, recording method, and recording apparatus

Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.

Liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus

To provide a liquid storage container equipped with a plug member that can prevent leakage of a liquid from the liquid storage container and can be opened without causing scatter of the liquid, and a liquid ejection apparatus equipped with the liquid storage container. For the purpose, at least one of a connection part of the convex part with the cover part and an apical part of the convex part most apart from the connection part is provided offset from the centroid of the cover part, seen from a direction orthogonal to an opening surface of a supply port in a state that the plug member is mounted on a supply port of the liquid storage container.

Liquid storage container and liquid ejection apparatus

Provided are an ink jet image forming method and an ink jet image forming apparatus in which a complex elastic modulus (Pa) before an intermediate image comes into contact with a liquid absorbing member is 4.0 or more in the common logarithm, and a complex elastic modulus (Pa) before the intermediate image comes into contact with the recording medium is 7.0 or less in the common logarithm.

Ink jet image forming method and ink jet image forming apparatus

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

Liquid container unit and recording apparatus

There are provided a liquid container including a plug member which prevents leakage of a liquid from the liquid container and can be opened without scattering the liquid and a liquid ejection apparatus including the liquid container. For that purpose, a projecting portion in the plug member is provided below a center part of the plug member in a gravity direction in an attitude at the time of use of the liquid ejection apparatus.

Liquid container and liquid ejection apparatus

A liquid supplying mechanism includes: a tank including a liquid storage section configured to store a liquid, and a liquid injection port configured to inject the liquid into the liquid storage section; and a bottle configured to replenish the liquid into the tank. The bottle includes: a bottle section configured to store the liquid; and a protruding section, which protrudes from the bottle section, and is insertable into the liquid injection port so as to inject, into the liquid storage section, the liquid stored in the bottle section. The liquid injection port includes: a protruding section insertion portion into which the protruding section of the bottle is insertable; and a protruding section fixing portion, which is engageable with the protruding section of the bottle, to thereby be capable of fixing the bottle to the tank.

Liquid supplying mechanism, and liquid ejection apparatus

A printing apparatus includes a printing head configured to eject a first ink and a second ink, wherein the second ink generates less deposition than the first ink, an ink absorber configured to absorb the ink ejected from the printing head, a detection unit configured to detect a state of the ink absorber through an optical method, and a control unit configured to cause the printing head to eject the second ink to the ink absorber based on a detection result of the detection unit.

Inkjet printing apparatus

An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.
