The first protrusions extend in parallel with a feed direction and are arranged at predetermined intervals in a direction perpendicular to the feed direction. The recesses are defined between adjacent ones of the first protrusions and extend in the feed direction. The second protrusions are provided on downstream and upstream sides, respectively, in the feed direction with respect to an image forming region and extend in the direction perpendicular to the feed direction. The two suction ports are defined on the downstream and upstream sides, respectively, in the feed direction with respect to the image forming region in each of the recesses. The suction ports communicate with the suction device.
