Abstract
An image forming apparatus comprises: a detection unit which detects a light amount of reflected light from a measurement image, and includes an irradiation unit which irradiates the measurement image with light, a first unit which receives specular light from the measurement image, and a second unit which receives diffused light from the measurement image; a controller which controls an image forming condition based on a detection result; and a determination unit which determines a first emission intensity based on a light amount of the specular light, and determines a second emission intensity based on the first emission intensity, the light amount of the specular light, and a light amount of the diffused light, wherein the emission intensity of light with which the irradiation unit irradiates the measurement image is controlled based on the second emission intensity.
