摘要： Printing plate production apparatus wherein a latent image is formed at the surface of photoconductive insulating sheet, either by an optical system for effecting sheet exposure or by a laser emission scanning system which constitutes the terminal of a facsimile transmission system, this latent image is developed by toner particles, for example, which are applied on, but not fixed on the photoconductive sheet, the developed image is temporarily transferred onto a printing plate with which the photoconductive sheet is brought into pressure contact, and the printing plate carrying the developed image is exposed to light which may effect chemical changes in the printing plate to harden portion thereof unprotected by toner particles after which the printing plate receives treatment to remove toner particles and unhardened portions thereof. In the means of the invention a sheet carrying a developed image initially transmitted by a single facsimile transmission system may be employed as a master copy which is mounted in the exposure system and serves in production of a plurality of identical printing plates.
