ABSTRACT:
Light scanning devices forming electrostatic latent images on photosensitive bodies are disposed so as to correspond respectively to the plurality of photosensitive bodies which correspond to a plurality of colors, respectively. Electrooptical elements are disposed on light paths of light beams. The electrostatic latent images formed on the respective photosensitive bodies 1 are respectively developed by developing means. Developed electrostatic latent images are respectively superposed together and transferred onto a sheet, so that a color image is formed. Images-for-detecting-offset-amounts, which are formed on a conveying body by the light scanning devices, are detected, and offset amounts of images of the respective colors are detected. Based on detected offset amounts, voltages are applied to the respective electrooptical elements such that the offset amounts become values of a predetermined range.
