PROBLEM TO BE SOLVED: To provide an optical sensor that can obtain information for determining an object in detail compared with a prior art.SOLUTION: An optical sensor 2245 comprises: an irradiation system 10 that irradiates a recording sheet with linearly polarized light in a predetermined polarization direction from a direction inclined with respect to the recording sheet; detection means including a light receiving unit 14 (detection system) that individually detects a plurality of rays of light emitted from the irradiation system 10 and reflected on the recording sheet in directions different from each other; and a driving system that changes the positions of the irradiation system 10 and light receiving unit 14.SELECTED DRAWING: Figure 6 【課題】 対象物を従来よりも細かく判別するための情報を得ることができる光学センサを提供する。【解決手段】 光学センサ２２４５は、所定の偏光方向の直線偏光を記録紙に該記録紙に対して傾斜した方向から照射する照射系１０と、該照射系１０から照射され記録紙で互いに異なる方向に反射された複数の光を個別に検出する、受光器１４（検出系）を含む検出手段と、照射系１０及び受光器１４の位置を変更する駆動系と、を備えている。【選択図】図６
