Summary:An optical sensor includes a light source; and an optical detector detecting intensity of light that is reflected by a recording medium, the light from the light source and irradiated onto the recording medium. Further, when an incident angle of the light incident to the recording medium from the light source relative to a normal line of the recording medium is given as θ1, a formula 75°≤θ1≤85° is satisfied.
