PURPOSE:To improve operability and to facilitate the handling of an electronic blackboard by electrifying and forming the latent image of original information inputted to the dielectric membrane of a blackboard sheet, attracting toner to the image and developing image by semi-fixing or fixing with heat. CONSTITUTION:An electrostatic head 4 has a writing-in electrode 4a and a control electrode 4b, electrifies the blackboard sheet 1 by means of the writing-in electrode 4a according to writing-in information from a control part 5 to form the latent image. The electrostatic head 4, a developing roll 8 constituting the developing means 6 and a fixing lamp 9 are arranged in a region where the blackboard sheet 1 at the bottom of a device is guided by a direction inverting guide 10 in order from the side of a lower roller 3. The development of the latent image is executed by the attraction of the toner attracted by the magnetism to the developing roll 8 and the toner is softened by the fixing lamp 9 to fix the toner. Thus operability is improved to facilitate the handling. |
