Abstract

PURPOSE:To obtain a device which has superior stability without using a photoreceptor by providing a picture display belt and a signal electrode group close to it to supply a toner between them and impressing a signal voltage in a picture shape to stick the toner to the display belt. CONSTITUTION:An endless type image carrier 4 is extended to rolls 5, 6, and 7 in a device outer housing 1. A light transmissive belt 4 has a conductive layer 42 on the external surface of a base layer 41 and an insulating thin layer 43 is formed thereupon. A brush T is formed by a toner container 9 opposite to a magnet roll 8 and when no signal is impressed to a signal electrode 10, the toner is not stuck to the external surface of the belt 4 to be carried out; when a signal voltage is impressed, the toner of the toner brush at the electrode part is charged, and some of the toner sticks T2 by coulombic force. Consequently, picture information to be displayed is formed as a toner picture successively on the external surface of the belt 4 according to the rotation of the belt 4. Consequently, high-contrast display and color display are obtained.

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.
