摘要： An apparatus and method of forming a color image on a recording sheet by transferring respective images onto a single recording sheet conveyed by a conveying belt, where the combination of the respective images form the color image. The respective color images are formed with a plurality of electrophotographic processing sections disposed along the conveying belt such that the respective color images are superimposed on one another to make the color image. The electrophotographic processing sections also form more than two colors, of a same pattern, of image positional deviation detecting marks. The image positional deviation detecting marks include a line in a main scanning direction and another line positioned at an incline with respect to the former line in order on the conveying belt. A detector is included that detects the image positional deviation detecting mark with a single detecting device composed of a light source, a slit, and a light accepting element.
