ABSTRACT:
An imaging belt, a dielectric recording sheet, a charger, a transcript roller, and first and second rollers are arranged in a casing. A latent image corresponding to a radiation transmitted image is formed on the imaging belt. At least a fluorescent layer which is sensitive to a radiation to emit light, and a photosensitive layer sensitive to the light emitted by the fluorescent layer are formed on a flexible substrate to constitute the imaging belt. The imaging belt is looped around the first and second rollers, and is driven to rotate. The dielectric recording sheet is rolled, and the latent image formed on the photosensitive layer of the imaging belt is transcribed onto the dielectric recording sheet. The charger charges the surface of the imaging belt at a high voltage. The transcript roller urges the dielectric recording sheet against the imaging belt. Then, the latent image formed on the imaging belt is transcribed onto the dielectric recording sheet.
