The present invention relates to an aqueous gravure ink containing a pigment, a water-soluble organic solvent, a surfactant and water, in which the water-soluble organic solvent contains a glycol ether having a boiling point of 100 to 260° C.; the surfactant contains a silicone-based surfactant containing a specific constitutional unit; a content of the water-soluble organic solvent in the ink is 1 to 10% by mass; and a content of water in the ink is 50 to 80% by mass. This ink exhibits a less burden on the environments, and is excellent in optical density and drying properties.

A device includes a media supply, a first portion, and a second portion. The media supply is to supply a media along a travel path and to which a ground element is to be electrically connected. The first portion along the travel path is to receive droplets of ink particles within a dielectric carrier fluid on the media to form at least a portion of an image on the media. The second portion is downstream along the travel path from the first portion and includes a charge generation portion to emit airborne charges to charge the ink particles to move, via attraction relative to the grounded media, through the received carrier fluid toward the media to become electrostatically fixed on the media.

An ink contains water, an organic solvent, and a resin having a glass transition temperature Tg of from 0 to 70 degrees C., wherein a contact angle θ1 of the ink against a vinyl chloride resin film and a contact angle θ2 of the ink against an ink image formed with the ink satisfies the following relationship: θ1<θ2.
