Abstract
A first and second electrostatic image code is located outside a developing zone. A transfer belt provided with an electrostatic image recording track capable to transfer the electrostatic code between the first drum and second drum. A transferring voltage applies to a side of the transfer belt for the first drum to transfer the first electrostatic image code onto the electrostatic image recording track. An electroconductive member is in parallel with the electrostatic image code and a surface of the electrostatic image code detected within a predetermined gap. An induced current generated in the electroconductive member relative to the lines of the electrostatic image codes which control the first drum or the second drum on the basis of a detection result of the detecting means such that the toner image on the second drum transferred onto a recording material on the transfer belt and overlaid on the toner image transferred onto the recording material from the first drum.
