PROBLEM TO BE SOLVED: To provide an ink-jet recording device which can detect the positions of edges of a recording medium in the width direction with a good precision.SOLUTION: A printer (ink-jet recording device) 100 of the present invention comprises: a first belt conveyor part 5 to convey a sheet P; a recording part 9 to discharge ink to the sheet P conveyed by the first belt conveyor part 5; an edge position detection sensor 60 disposed upstream of the first belt conveyor part 5 in the sheet conveyance direction and utilizing reflected light to detect the positions of edges of the sheet P in the sheet width direction crossing the sheet conveyance direction; and a background member 61 opposed to a detection surface of the edge position detection sensor 60 and rotatable about an axis extending in the sheet width direction. An outer peripheral surface of the background member 61 has, at least in a region opposite the detection surface of the edge position detection sensor 60, two or more regions 61c, 61d colored different from each other and formed to partition the outer peripheral surface in the circumferential direction.SELECTED DRAWING: Figure 7 【課題】記録媒体の幅方向の端部の位置を精度良く検出することが可能なインクジェット記録装置を提供する。【解決手段】このプリンター（インクジェット記録装置）１００は、用紙Ｐを搬送する第１ベルト搬送部５と、第１ベルト搬送部５により搬送される用紙Ｐへインクを吐出する記録部９と、第１ベルト搬送部５に対して用紙搬送方向上流側に配置され、用紙Ｐの用紙搬送方向と交差する用紙幅方向の端部の位置を、反射光を利用して検出する端部位置検出センサー６０と、端部位置検出センサー６０の検出面に対向配置され、用紙幅方向に沿って延びる軸を中心として回転可能な背景部材６１と、を備える。背景部材６１の外周面には、少なくとも端部位置検出センサー６０の検出面に対向する領域に、互いに異なる色を有する２つ以上の領域６１ｃ、６１ｄが外周面を周方向に分割するように形成されている。【選択図】図７
