PROBLEM TO BE SOLVED: To suppress blurring, striking-through and offset when performing high-speed printing as well.SOLUTION: An inkjet recording device 1 comprises three or more predetermined number (herein, set to four) of recording heads 34 (34a, 34b, 34c and 34d), a conveying part 31 and a negative pressure applying part 33. The four recording heads 34 discharge four ink respectively onto a recording paper P. The conveying part 31 conveys the recording paper P to a position where an image is formed by the four recording heads 34. The negative pressure applying part 33 applies negative pressure to spaces 341a-341d between the four recording heads 34 and the conveying part 31 (a conveying belt 32). The negative pressure applying part 33 sets negative pressure applied to the space 341a of the recording head 34a arranged at the most upstream side and the space 341d of the recording head 34d arranged at the most downstream side with respect to a conveying direction of the recording paper P, higher than negative pressure applied to the spaces 341b and 341c of the other recording heads 34b and 34c.SELECTED DRAWING: Figure 2 |
