Abstract
An image forming apparatus includes a latent image bearer; a writing device configured to write a latent image onto the latent image bearer; a detection device configured to detect, at a plurality of positions, a density of a toner image obtained through development of the latent image; and a controller configured to correct a writing intensity of the writing device to correct an uneven density based on detection values of the detection device. The controller determines whether each of the detection values is pass or fail. In response to a determination that a detection value is fail, the controller corrects the wiring intensity based on another detection value determined to be pass at a position different from a position at which the detection value is determined to be fail, instead of correcting the writing intensity based on the detection value determined to be fail.
