  • a recording head including nozzles that eject ink droplets onto a sheet that is conveyed in a conveying direction through a transport path;

    a plurality of first conveyors spaced apart from each other with respect to a scanning direction orthogonal to the conveying direction, and wherein the plurality of first conveyors includes a first nip member and a second nip member defining a first nip point therebetween, and wherein the first nip point of the plurality of first conveyors located downstream of the nozzles with respect to the conveying direction;

    a first spur roller disposed between a pair of the first conveyors with respect to the scanning direction, and wherein a lower end of the first spur roller is located downstream of the first nip point of the plurality of first conveyors in the conveying direction, and wherein the first spur roller is configured to contact the sheet and form a corrugated shape in the sheet in conjunction with the plurality of first conveyors;

    a second spur roller, wherein a lower end of the second spur roller is located downstream of the lower end of the first spur roller in the conveying direction, wherein the second spur roller at least partially overlaps with the first spur roller when viewed in the conveying direction, and wherein the second spur roller is configured to maintain the corrugated shape in the sheet in conjunction with the first spur roller and the plurality of first conveyors; and

    a plurality of second conveyors spaced apart from each other with respect to the scanning direction, and wherein the plurality of second conveyors includes a first nip member and a second nip member defining a second nip point therebetween, and wherein the second nip point of the plurality of second conveyors is located downstream of the lower end of the second spur roller with respect to the conveying direction.
