Abstract
An image forming apparatus includes an image forming unit configured to form an image on an intermediate transfer member; a transfer member configured to output a transfer voltage in order to cause a transfer current to flow so as to transfer the image to a sheet; a measurement unit configured to measure a density of the image; and a control unit configured to control the image forming unit to form a test image on the intermediate transfer member based on test image data, control the measurement unit to acquire a measured density of the test image, correct the measured density based on an evaluation value of an electric resistance of a path through which the transfer current flows, and generate data for density correction based on the test image data and a corrected measured density.
