摘要:
A heat sealable printing sheet (1) includes a sheet-shaped base member (50), and an ink receiving layer (53) disposed on a first surface of the base member (50) and having a heat sealability. The heat sealable printing sheet (1) further includes a heat sealable layer (52) disposed on a second surface of the base member (50) and made of a heat sealable resinmaterial. The ink receiving layer (53) contains inorganic fine particles, a water soluble resin, and a water dispersible resin. The water dispersible resin has a glass transition temperature (Tg) satisfying -35°C≤Tg≤35°C.

There are provided a liquid accommodating container (30) that has a sufficient volume for reserving waste ink and can accommodate therein a sufficient amount of ink used in printing with space-saving, a liquid ejecting device provided therewith and a liquid introducing method. Therefore non-print ink is discharged and reserved in a portion, in which unused ink for printing was reserved, in an ink tank for replacement of the unused ink.

The present invention intends to provide a printing apparatus that can lessen a reduction in ejection performance caused by thickening, solidification, or the like of print liquid in an ejection port of a printing unit even in the case of stopping a print operation by the printing unit to perform a post-process on a print medium. The printing apparatus includes a post-processing part configured to, in a state of stopping the print operation by the printing unit, perform the post-process on a printed print medium as well as including an open/close unit configured to selectively perform a closing operation or an opening operation of the ejection port provided in the printing unit. Further, when the print medium is stopped in the post-processing part, the open/close unit is controlled so as to bring the ejection port into a close state.

An ink jet recording ink including a pigment; water; and water-soluble compounds. The pigment comprises a resin-dispersed pigment dispersed with a (meth)acrylate-based random copolymer having an acid value of 100-160 mgKOH/g. The water-soluble compounds include at least ethylene urea and a water-soluble compound having a hydrophilicity-hydrophobicity coefficient defined by the following equation (A) of 0.37 or less The total content of the water-soluble compounds is 22-50 mass% with respect to the total amount of the ink The content of the ethylene urea is 11.0 mass% or more with respect to the total amount of the ink, and the proportion of the amount of the ethylene urea in the total amount of the water-soluble compounds is 50% by mass or less, Hydrophilicity - hydrophobicity coefficient = water activity value of 20 % aqueous solution - molar fraction of water in 20 % aqueous solution / 1 - molar fraction of water in 20 % aqueous solution
摘要:
A recording medium, including: an ink-receiving layer configured to receive an ink for inkjet recording; and a transparent sheet having a total luminous transmittance of 50% or more, wherein the recoding medium has a layered structure in which the transparent sheet and the ink-receiving layer are sequentially stacked, and the ink-receiving layer includes a gap-absorption-type ink-receiving layer including a composition including at least inorganic fine particles and polyvinyl alcohol having a weight-average polymerization degree of 2,000 or more and 5,000 or less and a saponification degree of 70 mol% or more and 90 mol% or less.

To prevent a flap (Pb) of an envelope (P) to stick to an envelope main body (Pa), provided is an image forming apparatus including: an image forming portion forming a toner image on the envelope; a fixing device fixing the toner image onto the envelope by heating the envelope while conveying the envelope on which the toner image is formed by the image forming portion; and a conveying roller pair (235) that rotates while nipping the envelope, onto which the toner image is fixed by the fixing device, to convey the envelope. A driven roller (233) of the conveying roller pair includes driven runners (331, 332) divided in a rotary shaft center direction, and one driven runner (332) located at one end is inclined in a direction separating from another driven runner (331) so that an outer peripheral surface (332a) of the one driven runner is brought into contact with a corner portion (22b) of a rubber roller (262).
