Abstract:
1. An image forming apparatus comprising: a plurality of image forming sections that forms images of different colors, respectively; a correction image formation controlling section that forms correction images, for density correction and color deviation correction, of the respective colors, by causing the image forming sections to draw the correction images and transferring the correction images onto an image carrying body; a density sensor that detects a density of each of the correction images in synchronization with passage of each of the correction images on the 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 a density of an image of a color whose density is abnormal, based on the detected density of each of the correction images; and a color deviation correction controlling section that corrects and controls a color deviation of an image of a color in which color deviation occurs, based on the detected position of each of the correction images, wherein
