Abstract:
A recording medium determining device includes a light irradiating portion that irradiates a recording medium with visible light; a regular reflection light receiving portion that receives regular reflection light regularly reflected by the recording medium irradiated with light from the light irradiating portion; a diffused reflection light receiving portion that receives diffused reflection light diffusely reflected by the recording medium irradiated with light from the light irradiating portion; and a determining portion that determines the type of recording medium on the basis of each light amount of two or more visible light components with different wavelengths to one another among the light components received by the regular reflection light receiving portion and each light amount of two or more visible light components with different wavelengths to one another among the light components received by the diffused reflection light receiving portion.
