Abstract
An image forming apparatus includes a measurement unit configured to emit light to a measurement target, and measure reflected light from the measurement target; a white reference plate disposed at a position opposed to the measurement unit; an image forming unit configured to form a measurement image on a sheet; and a calculation unit configured to, based on a measurement value of the white reference plate and a measurement value of the measurement image by the measurement unit, calculate a spectral reflectivity of reflected light from the measurement image. The calculation unit is configured to, after correcting a variation due to color change of the white reference plate with respect to the measurement value of the white reference plate, calculate the spectral reflectivity.
