PURPOSE:To confirm visually an unfixed image which is formed on a belt-shaped photosensitive body easily on a plane screen part by flattening a part of the belt-shaped photosensitive body to position the part to be observed directly from the outside of a device. CONSTITUTION:The photosensitive body 2 is wound around a take-up roller 6 from a supply roller 1 through guide rollers 3-5, and the optical image of an original 9 to be enlarged and displayed is enlarged and is irradiated to the photosensitive body 2 by an exposure device 8 to form an electrostatic latent image after the photosensitive body 2 is electrostatically charged by an electrostatic charger 7. This image is developed by a magnet brush developing device 10 and is positioned for example, between guide rollers 4 and 5 to be observed by person to emable him see directly from the outside of the device. Thus, the original which is difficult to see with a naked eye is displayed quickly and vividly not to give an unnatural impression to him because the original is displayed similarly to a copy paper. |
