Abstract
A test image is formed by an image forming unit. A sensor receives light reflected from a test image on an intermediate transfer member passing through a detection position and outputs an output signal based on a reception result of the reflected light. A controller reduces density unevenness of images to be formed in a rotation direction of a photosensitive member based on a correction data, determines a reference output signal used to generate the correction data among output signals output from the sensor in time series based on a timing at which the test image reaches the detection position.
