Patent number: 10723158Abstract: A line head type liquid discharge apparatus includes a treatment liquid applying device, a first discharging device, a heating device, and a second discharging device. The treatment liquid applying device applies a treatment liquid to a non-permeable base material. The first discharging device discharges a first ink containing an organic solvent onto the non-permeable base material to which the treatment liquid has been applied. The heating device heats, with an infrared ray, the non-permeable base material onto which the first ink has been discharged. The second discharging device discharges a second ink containing an organic solvent onto the non-permeable base material heated by the heating device. A content ratio of the organic solvent contained in the first ink is higher than a content ratio of the organic solvent contained in the second ink.Type: GrantFiled: March 25, 2019Date of Patent: July 28, 2020Assignee: Ricoh Company, Ltd.Inventors: Naohiro Toda, Takuma Nakamura, Yukie Inoue, Masaya Hamaguchi, Hiroyuki Yamashita
