Abstract
An ink mist recovery device allows suction of ink mist with uniform suction force irrespective of a position on a confronting sheet. The ink mist recovery device includes a recovery casing having multiple suction ports confronting a sheet, and a suction unit connected to the recovery casing. At least one of a size of each of the suction ports and a first suction distance from each of the suction ports to a suction slit is set in accordance with a second suction distance from the suction unit to the suction slit via each of the suction ports so that the suction force is kept uniform at the respective positions on the sheet corresponding to the suction ports. The mist suction force is made uniform over the entire width of the suction slit to improve quality of the printed image without sucking ink droplets required to land.
