发明名称 IMAGE FORMING APPARATUS
摘要 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.

主权项 1. An image forming apparatus comprising: an image carrier; an image forming unit configured to form an image on the image carrier using a developing agent; a detection unit configured to detect a light amount of reflected light from a measurement image formed on the image carrier by the image forming unit, the detection unit includes an irradiation unit configured to irradiate the measurement image with light, a first light receiving unit configured to receive specular light from the measurement image, and a second light receiving unit configured to receive diffused light from the measurement image; a controller configured to control an image forming condition based on a detection result by the detection unit; and a determination unit configured to make the irradiation unit to irradiate the image carrier using the light, make the first light receiving unit to receive specular light from the image carrier, make the second light receiving unit to receive diffused light from the image carrier, determine a first emission intensity based on a light amount of the specular light from the image carrier, and determine a second emission intensity based on the determined first emission intensity, the light amount of the specular light from the image carrier, and a light amount of the diffused light from the image carrier, wherein the emission intensity of light with which the irradiation unit irradiates the measurement image is controlled based on the second emission intensity determined by the determination unit.
