Abstract
An image forming apparatus that is capable of finding density of an output image with high accuracy even if reflectance of an image bearing member varies. A conversion unit converts image data based on a conversion condition. An image forming unit forms an image based on the converted image data. A measurement unit measures irregular reflection light from a measurement image on the image bearing member. A controller controls the image forming unit to form measurement images, controls the measurement unit to measure irregular reflection light from an area on the image bearing member where the measurement images are not formed, controls the measurement unit to measure the irregular reflection light from the measurement images, selects a measurement result from among measurement results of the measurement images based on the measurement result of the area, and generates the conversion condition based on the selected measurement result.
