Patent number: 11491783Abstract: 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.Type: GrantFiled: February 22, 2021Date of Patent: November 8, 2022Assignee: KYOCERA Document Solutions Inc.Inventors: Takeshi Watanabe, Hiroyuki Ueda, Hiroatsu Tamai, Takatoshi Nishimura, Noriaki Ozawa, Toyotsune Inoue, Susumu Hiroshima
