An ink-jet recording apparatus includes: an image recorder; a first supporter including support ribs extending to positions under the image recorder; an ink receiver disposed downstream of the support ribs; first and second roller pairs disposed downstream of the first supporter; a guide; and a protrusion disposed between the ink receiver and the first roller pair and having an upper end located below upper ends of the support ribs and above a first imaginary line connecting between a nip position of the first roller pair and a downstream end of the ink receiver. A distance between an upstream end of the ink receiver and a nip position of the second roller pair is less than a length of a first-size sheet and greater than a length of a second-size sheet. The protrusion is disposed, in a widthwise direction, in a region through which the second-size sheet is conveyed.
