    Abstract: A sensor IC of the present invention is provided with plurality of light receiving portions arranged in a row along a primary scanning direction and including a first light receiving portion for receiving light of a first wavelength, a second light receiving portion for receiving light of a second wavelength different from the first wavelength, and a third light receiving portion for receiving light of a third wavelength different from the first wavelength and the second wavelength. The sensor IC further includes a control circuit that outputs a first electric signal corresponding to light of the first wavelength received by the first light receiving portion, a second electric signal corresponding to light of the second wavelength received by the second light receiving portion, and a third electric signal corresponding to light of the third wavelength received by the third light receiving portion.
