To provide a sheet conveying device, an image forming device and a determining method that can determine an amount of fluffing in a sheet.SOLUTION: An image forming device 100 comprises: a pressing member that is pressure-contacted with a sheet to convey the sheet; a first obtaining processing part 61 that obtains a first specific value corresponding to variations of reflectance of light caused by contacting with the pressure member in the sheet; a second obtaining processing part 62 that obtains a second specific value corresponding to variations in a thickness caused by the contacting with the pressure member in the sheet; and a first determining processing part 63 that determines an amount of fluffing in the sheet, on the basis of the first specific value obtained by the first obtaining processing part 61 and the second specific value obtained by the second obtaining processing part 62.SELECTED DRAWING: Figure 2 【課題】シートにおける毛羽の起立量を判定可能なシート搬送装置、画像形成装置、及び判定方法を提供すること。【解決手段】画像形成装置１００は、シートに圧接してシートを搬送する加圧部材と、シートにおける前記加圧部材との接触による光の反射率の変化量に対応する第１特定値を取得する第１取得処理部６１と、シートにおける前記加圧部材との接触による厚さの変化量に対応する第２特定値を取得する第２取得処理部６２と、第１取得処理部６１によって取得される前記第１特定値及び第２取得処理部６２によって取得される前記第２特定値に基づいて、シートにおける毛羽の起立量を判定する第１判定処理部６３と、を備える。【選択図】図２
