A superimposed image forming apparatus, includes a plurality of electrophotographic photosensitive drums, toner image forming devices, provided for the respective photosensitive drums, for forming toner images on the respective photosensitive drums, image transfer devices, provided for the respective photosensitive drums, for transferring the toner images formed on the photosensitive drums onto a transfer material at respective image transfer stations, conveying devices for conveying the transfer material sequentially through the respective image transfer stations, and adjusting mechanisms for adjusting inclinations of rotational axes of the photosensitive drums. Thus, image inclination of a resultant image can be corrected by adjusting the inclination of the axis of the drum by an amount which is a half of the image inclination.
