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 ink includes a pigment, first particles containing a first resin, second particles containing a second resin, and a moisturizing agent. The first resin includes a repeating unit derived from methyl methacrylate at a content percentage of at least 30% by mass and no greater than 70% by mass relative to all repeating units included in the first resin. The second resin has a content percentage of the repeating unit derived from methyl methacrylate of less than 30% by mass relative all repeating units included in the second resin. The moisturizing agent includes an α,ω-alkanediol. An inkjet recording system includes a conveyance section and an inkjet recording head including a plurality of nozzles that eject the inkjet ink to form dots on a recording medium conveyed by the conveyance section.

Abstract: A decurling device includes a first conveyance path, a second conveyance path, a first switch, a decurler, and a controller. A sheet is conveyed along the first conveyance path or the second conveyance path. The first switch switches a route of conveyance of the sheet to the first conveyance path or the second conveyance path. The sheet has a first main surface and a second main surface. The decurler is located in the second conveyance path. The decurler corrects curl of the sheet. In a situation in which a weight per unit area of the sheet is smaller than a first threshold value, the controller controls the first switch such that the sheet is conveyed along the second conveyance path.
