Summary:An optical sensor includes a light source, and a light detector that irradiates a recording medium with light emitted from the light source to detect intensity of light reflected on the recording medium. When an incidence angle of the light incident on the recording medium from the light source with respect to a normal of the recording medium is represented as 75 DEG<=theta1<=85 DEG is satisfied. 一种光学传感器包括：光源；以及光学检测器，检测由记录介质反射的光的强度，所述光从光源发射且照射到所述记录介质上。另外，当从光源入射到记录介质的光相对于记录介质的法线的入射角被给定为θ1时，满足公式75°≤θ1≤85°。
