Abstract:
1. An image forming apparatus comprising: a conversion unit configured to convert image data using a conversion condition; an image forming unit configured to form an image based on the image data converted by the conversion unit, the image forming unit including an image carrier, an exposure unit configured to expose the image carrier to form an electrostatic latent image, a developing unit configured to develop the electrostatic latent image by using developing material that includes toner and carrier, and an intermediate transfer member onto which the image that is formed on the image carrier is transferred; a detection unit configured to detect a toner density of the developing material in the developing unit; a replenishing unit configured to replenish the toner in the developing unit; a replenishment control unit configured to, based on the toner density detected by the detection unit and a target density, control the replenishing unit; a measurement unit configured to measure a measurement image formed on the intermediate transfer member by the image forming unit; a first determination unit configured to control the image forming unit to form a first measurement image, control the measurement unit to measure the first measurement image, and determine the target density based on a measuring result of the first measurement image; a correction unit configured to control the image forming unit to form a second measurement image, control the measurement unit to measure the second measurement image, and correct the conversion condition based on a measuring result of the second measurement image and a correction condition; and a second determination unit configured to determine the correction condition based on the target density determined by the first determination unit.
