1. An image forming apparatus comprising:
a correction unit configured to correct image data based on a correction condition; an image forming unit configured to form an image based on the image data corrected by the correction unit; a measurement unit configured to measure a measurement image formed by the image forming unit; an update unit configured to control the correction unit to correct measurement image data based on the correction condition, control the image forming unit to form the measurement image based on the corrected measurement image data, and update the correction condition based on a measurement result of the measurement image by the measurement unit and reference data corresponding to the measurement image; and a control unit configured to control whether or not to convert a measuring result of a target measurement image among measurement images by the measurement unit to target reference data corresponding to the target measurement image, wherein the control unit is configured to, in the case where a value obtained by correcting image data for forming the target measurement image based on the correction condition is outside a predetermined range, convert the measurement result of the target measurement image to the target reference data.
