    Abstract: A control portion sets, as a control period, a period after arrival, at a position opposite a recording head, of a first recording medium until passage, at the position opposite the recording head, of a last recording medium. The control portion sets nozzles that do not face the recording medium during the control period as first nozzles, and nozzles that face the recording medium during the control period as second nozzles, to make the total amount of ink ejected by each of the first nozzles in flashing processing during the control period smaller than the total amount of ink ejected by each of the second nozzles.

    Abstract: When printing is performed on a recording medium of a second size larger than a first size, a control portion, after passage of the recording medium of the first size at a position opposite a recording head before arrival of the recording medium of the second size at the position opposite the recording head, makes the recording head perform preparatory flushing processing in which ink is ejected toward openings from first nozzles that have not been set as target nozzles during printing on the recording medium of the first size but will be newly set as the target nozzles during printing on the recording medium of the second size.

    Abstract: An inkjet recording apparatus includes memory, a processor, an image forming section, and a bending mechanism. The memory stores therein bending information in which a plurality of bending amounts corresponding to respective ejection amounts of an ink ejected from the image forming section are defined. The processor sets a bending amount of a sheet to be conveyed. The bending mechanism includes a roller and a belt that hold the sheet therebetween, and bends the sheet by moving a position of a center of the roller toward the belt based on the set bending amount. The processor calculates for each of areas of the sheet an amount of the ink ejected to the area, and sets the bending amount of the sheet based on the bending amounts corresponding to the calculated amounts of the ink ejected to the respective areas in the bending information.

    Abstract: An inkjet recording apparatus (1) includes an image forming section (40), a decurler (20), a changing section (50), a first calculating section (72), storage (60), a second calculating section (73), and a controller (75). The image forming section (40) ejects ink onto a sheet (S). The decurler (20) bends the sheet (S). The changing section (50) changes a bending amount of the sheet (S). The first calculating section (72) calculates an ink ejection rate (α) to the sheet (S) for each of areas of the sheet (S). The storage (60) stores therein first bending information (62) indicating a first target bending amount (β) of a specific area of the sheet (S) corresponding to the ink ejection rate (α) to the specific area. The second calculating section (73) calculates a second target bending amount of each of the areas. The controller (75) controls the changing section (50) based on the second target bending amounts.

    Abstract: An inkjet recording apparatus includes a recording head, a conveyance section, a plate member, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium to a position of image forming by the recording head and has a conveying surface on which the recording medium is to be placed. The plate member is located upstream of the recording head in a conveyance direction of the recording medium to form a narrow gap with the conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. A distance across the narrow gap in a direction perpendicular to the conveying surface is set so as to allow air flowing into the narrow gap from surrounding space to have a higher flow velocity in the narrow gap than before flowing into the narrow gap.

    Abstract: A degassing device removes air dissolved in a liquid under a pressure decreased atmosphere, and includes a liquid tank, a pressure decreasing device, a circulation flow pass, a circulation device, and a variable mechanism. The liquid tank stores the liquid. The pressure decreasing device decreases pressure in the liquid tank. The circulation flow pass communicates different positions of the liquid tank. The circulation device circulates the liquid through the circulation flow pass. The variable mechanism changes a height of an inlet port from the circulation flow pass to the liquid tank in accordance with a height of a liquid surface in the liquid tank.

    Abstract: An inkjet recording apparatus includes three or more recording heads. The recording heads contain different inks and eject the different inks sequentially on a recording medium. The different inks each contain a pigment. Of the different inks, an ink to be ejected first has the lowest pigment content ratio. Of the different inks, an ink to be ejected third and an ink to be subsequently ejected each have a pigment content ratio equal to or higher than that of the pigment contained in a corresponding one of inks to be precedently ejected. Of the different inks, an ink to be ejected second and an ink to be subsequently ejected each have a lower viscosity at 25° C. than a corresponding one of inks to be precedently ejected.

    Abstract: An inkjet recording apparatus includes a recording head, a conveyance section, a first voltage applying section, and a second power supplying section. The recording head ejects ink onto a recording sheet. The conveyance section conveys the recording sheet to a position of image forming by the recording head. The first power supplying section applies a voltage to the recording sheet upstream of the recording head in a conveyance direction of the recording sheet. The second power supplying section includes a plate member located between the recording head and the first power supplying section and applies a voltage to the plate member that is of opposite polarity to the voltage applied by the first power supplying section.
