Abstract
An image forming apparatus includes image forming sections that forms images of different colors, respectively, a correction image formation controlling section that forms correction images of the respective colors, a density sensor that detects a density of each of the correction images in synchronization with passage of each correction image on an image carrying body, a detecting section that detects a position and the density of each of the correction images, based on a binary signal of a density detection output of each of the correction images, a density correction controlling section that corrects and controls an image density of the color, based on the detected density of each of the correction images, and a color deviation correction controlling section that corrects and controls the color deviation, based on the detected position of each of the correction images.
