    摘要: in a developing head in which the liquid developer or the liquid developer and the squeezing gas are applied by means of a feeding system to the photosensitive surface of the electrophotographic material for electrophotographic apparatus via the developing chamber, the developing head for electrophotographic apparatus comprises:

    a space made between the framed opening (2a) of the developing mask means (2) at its outer peripheral surface and the opposing photosensitive surface (3a) to prevent leakage of the liquid developer by capillarity from the interval between the photosensitive surface and the framed opening (2a) of the developing mask means (2) at its mouth abutting on said surface (3a);
    a valve (17) interposed in between the passageways for feeding the liquid developer and the gas, respectively, in order to prevent the liquid developer from flowing into the passageway for supplying the gas;
    a pressure reduction means to apply negative pressure to an interval made between the photosensitive surface (3a) and the mouth of the framed opening (2a) when the electro- photographic material (3) is forwarded for one frame.

    摘要: The method and apparatus make a printing plate such as a lithographic printing plate by exposing an original plate of the printing plate such as a presensitized plate in a substantially oxygen-free state. The method and apparatus deprive substantially of oxygen at least an exposed area of the original plate being exposed to light at least during exposure and expose the original plate to the light at a wavelength of between 250 nm and 420 nm. The original plate has on a support an image recording layer containing a polymerization initiator, a polymerizable compound and a binder polymer, being sensitive to the light at the wavelengths of between 250 nm and 420 nm, having no oxygen barrier layer, and being removable with a printing ink and/or a fountain solution. That is, a latent image is formed by photo-polymerization on the original plate and the original plate is subjected to development on a printing press.

    摘要: A method of developing a photosensitive planographic printing plate which includes a support and a recording layer and which has been exposed to a light beam with a developer, wherein the photosensitive planographic printing plate is immersed in the developer while being conveyed, and development is accelerated by brushing the immersed photosensitive planographic printing plate with a brush member produced by winding, around a peripheral surface of an axially rotating roller, a brushing band composed of a sheet-like substrate containing a hairy material woven therein.
