対向するマグネットローラ位置に磁極Sを配設すると。The toner image that has finished being displayed rotates back to the toner container 9 as the belt 40 is braked, and is erased by contact with the toner in the container 9, and a new toner image is formed on the belt surface by the signal electrode group 10. The previously displayed image will not appear as a ghost image. If necessary, for example, the lower edge 91 of the rear wall of the toner container 9 may be made of a magnetic material, and the magnetic pole S may be disposed at the position of the magnet roller facing it.

補給等のメンテナンスは不要である。The toner of the image formed on the belt surface returns to the toner container 9, is collected together with the toner in the container, and is repeatedly used to form toner images. Therefore, the toner in the container 9 is not substantially consumed, and maintenance such as toner replenishment is not required.

By mixing 100 million colors, it is recognized as white or grayish white. When non-transparent toner (black) is selectively applied to the six-color filters 44R, 44G, and 44B of the 6-color filters 44R, 44G, and 44B, the belt surface becomes a portion hidden by the toner. For example, except for the red filter 44R, other green and blue filters 44G
・44 B 7Mi is applied with toner, and the scraps and the velsit surface t ÷ 11 minutes are recognized as red, and when toner is applied only to the filter 44B, the remaining red and green fill 44 R・44G By mixing the colors of , the bell) and surface parts are recognized as yellow.

を近いものにしておく事が望ましい。In the color light display station, if the positional relationship between the striped color filter sections 44R, 44G, 44B of the image display belt 40 and the corresponding individual signal skewers and poles 10 is misaligned, different colors will appear. Therefore, the belt drive means etc. should be moved to prevent the single image display belt from shifting laterally. Further, it is desirable that the thermal elongation ratio between the image display belt 4 and the support for the signal electrodes 10 be close to each other.
