PROBLEM TO BE SOLVED: To provide an apparatus for detecting a recording material capable of improving the accuracy for discriminating a surface state of a recording material, and an image forming device.SOLUTION: An apparatus 60 for detecting a recording material includes light guide means 67L, 67R for making a first light emitted by a first light source 61L and a second light emitted by a second light source 61R incident on a surface of a recording material respectively from two directions which are not in parallel when viewed in a normal direction of the recording material surface, to output information on the surface state of the recording material on the basis of an output of imaging means 63 imaging irradiated areas of the first light and the second light on the recording material. The second light source 61R is the same type as the first light source 61L. When the first and second light sources 61L, 61R are viewed in a direction along the center optical axes thereof, they are arranged in a relationship where respective reference lines of rotational phases around the center optical axes of the first and second light sources 61L, 61R are rotated in opposite directions at approximately the same angle with respect to a straight line perpendicular to an arrangement direction of the first and second light sources 61L, 61R. |
