PROBLEM TO BE SOLVED: To provide an image forming device that executes printing properly.SOLUTION: A frame body 24 is a partitioning member arranged around an intermediate transfer belt 21, and arranged along both sides in a width direction of the intermediate transfer belt 21. The frame body 24 mainly includes a pair of side boards 24a, and a pair of belt covers 24b. The pair of side boards 24a are arranged to cover a lateral end part of the intermediate transfer belt 21. The pair of belt covers 24b, which are close to an outer periphery 21a of the intermediate transfer belt 21, cover the outer periphery 21a of the intermediate transfer belt 21. Thus, an air flow 29 is generated above the intermediate transfer belt 21 and the frame body 24. Even if negative pressure is generated above the intermediate transfer belt 21 and the frame body 24, the air in the frame body 24 never flows to the outside of the frame body 24. |
