ABSTRACT:
An electrographic photocomposing machine including a rotary type carrier with negative images of characters and an electrophotographic section including a cylindrical intermediate image carrier with a drive. The intermediate image carrier has its surface coated with a photoconductive layer and a dielectric layer transparent in the sensitive area of the photoconductive layer. The electrophotographic section also includes a charging device having a main and two additional chargers arranged in direct proximity to the intermediate image carrier. Therewith, the luminous flux carrying the image of characters from the type carrier projects them on the intermediate image carrier portion between the additional chargers. In addition, the charging device has a main lamp for exposure of the intermediate image carrier, illuminating the latter in the area of action of the main charger, and an additional lamp for exposure of the intermediate image carrier, arranged downstream of the additional chargers in the direction of rotation of the intermediate image carrier.
