PROBLEM TO BE SOLVED: To provide an inkjet recording device capable of highly precisely detecting the position of an edge in a width direction of a recording medium.SOLUTION: A printer (inkjet recording device) 100 includes: a first belt transportation unit 5 that transports paper P; a recording unit 9 that jets ink to the paper P which is transported by the first belt transportation unit 5; an edge position detection sensor 60 that is disposed on an upstream side in a paper transportation direction with respect to the first belt transportation unit 5, and detects the position of the edge in a paper width direction crossing the paper transportation direction of the paper P by utilizing reflection light; and a polygonal prism-shaped background member 61 that is oppositely arranged to the detection surface of the edge position detection sensor 60 and can be rotated with an axis extending along the paper width direction as a center. On the outer peripheral surface of the background member 61, in at least an area opposed to the detection surface of the edge position detection sensor 60, two or more areas 61c and 61d having different colors from each other are formed so as to divide the outer peripheral surface in a 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多角柱状の背景部材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
