[0042] The overall structure of an inkjet printer
[0043] will refer to figure 1 The overall structure of the inkjet printer 10 according to the first embodiment will be described. The inkjet printer 10 is a line printer that prints image lines on the surface of the sheet P by ejecting different kinds of liquids R1 and R2 on the surface of the sheet P as the conveying unit 12 conveys the sheet P as a recording medium ( line printer). The liquids R1 , R2 are respectively stored in liquid containers 14 a , 14 b which are compartments integrally formed in the liquid cartridge 16 . The liquid cartridge 16 is mounted to the cartridge mounting portion 18 in a movable manner along the cartridge mounting portion 18 . In addition, the inkjet printer 10 includes: a plurality of (for example, 2) liquid applicators (applicator) 20a, 20b that apply liquids R1, R2 to form image lines; and a plurality of (for example, 2) communication paths 22a, 22b, which connects the liquid containe...

[0090] will refer to Figure 7 A second embodiment of the present invention will be described. The inkjet printer 110 according to the second embodiment has liquid containers 14 a , 14 b respectively containing the black ink R1 and the treatment agent R2 for coagulating or precipitating the black ink R1 . In addition, the inkjet printer 110 also has a plurality (for example, two) of liquid application sections, which are inkjet heads 20a for ejecting the black ink R1 on the surface of the sheet P, and applying rollers 112 to The treatment agent R2 is applied to the liquid application portion 114 on the surface of the sheet P. As shown in FIG. The application roller 112 is rotatably arranged in the agent storage 116 containing the treatment agent R2. The agent storage unit 116 is connected to a sub-tank 118 temporarily storing the treatment agent R2. Furthermore, a sub-tank 118 is connected to the downstream end of the communication path 22b. Therefore, the processing agent...

[0093] will refer to Figure 8 A third embodiment of the present invention will be described. The inkjet printer 120 according to the third embodiment has a plurality of (for example, three) liquid containers 14 a , 14 b , 13 c respectively containing ink R1 , treatment agent R2 , and humidifying liquid R3 . In addition, the inkjet printer 120 also has a plurality (for example, three) of liquid application sections, which are the inkjet head 20 a for ejecting the ink R1 , the spray head 20 b for ejecting the treatment agent R2 , and the humidifying section 125 . The liquid container 14c is similar in construction to the liquid containers 14a, 14b, and components similar to the liquid containers 14a, 14b will use like reference numerals.
[0094] The humidification part 125 includes: a vaporization unit 122 that vaporizes the humidification liquid R3; and a humidification application part 124 that supplies the vaporized humidification liquid R3 to the inkjet head 20a and the s...
