Abstract
An image forming apparatus includes an image forming device, a density deviation detector, and processing circuitry. The circuitry performs a density deviation adjustment mode to: cause the image forming device to form a first image pattern having a uniform image density in the width direction on a surface of an image bearer; cause the detector to detect a first image density deviation in the width direction in the first pattern; adjust the first deviation based on a detection result of the first pattern; cause the image forming device to form a second image pattern on a surface of the image bearer after adjustment of the first deviation; cause the detector to detect a second image density deviation in the width direction in the second pattern; and correct a light intensity sensitivity in adjusting the second deviation, based on a detection result of the second pattern.
