Abstract
An image forming apparatus with a correction function for correcting density of an image, including: an image bearing member configured to convey the image in a first direction; and a controller configured to perform a bias correction and a γ correction for the density, wherein the controller includes: a test patch generator configured to generate on the image bearing member a test patch including a first test patch and a second test patch; a first density sensor configured to detect density of the first test patch; a second density sensor configured to detect density of the second test patch; a selector configured to select one of a first detection signal from the first density sensor and a second detection signal from the second density sensor as a bias-correction detection signal and another detection signal as a γ-correction detection signal.
