An image reading device includes a first light source, a first image sensor, a second light source, a second image sensor, and processing circuitry. The first light source irradiates an object with light in a first wavelength range. The first image sensor receives light reflected by the object and output a first image. The second light source irradiates the object with light in a second wavelength range different from the first wavelength range of the first light source. The second image sensor receives light reflected by the object and output a second image. The processing circuitry calculates signal levels of the first and second image, controls light amounts of the first and second light source respectively based on the calculated signal levels, and detects abnormal lighting of the first or second light source corresponding to the first or second image sensor.
