Abstract
An apparatus for developing photosensitive material which comprises passing the material into a bath of circulating developer fluid at a relatively static portion thereof and discharging the material from the bath below the surface of the fluid through a nip between two squeeze rollers. The fluid is prevented from escaping from the bath at the discharge end due to the cooperation between a sealing lip on the lower guide plate of the bath and the nip formed by the squeeze rollers.
Claims5
Apparatus for the liquid development of electrophotographic reproduction material, comprising a bath of developer liquid delimited by side walls, a bottom of a slightly curved support, a sealing lip, and a pair of squeeze rollers positioned near a lower end of said support, which support is adapted to guide said reproduction material in said developer liquid,
- a circulation system of circulating said developer liquid including a spraying pipe arranged above the open upper surface of said developer liquid, said spraying pipe being positioned near said squeeze rollers and partially screened by a baffle against said slightly curved support,
- and said developer liquid being dammed up by said pair of squeeze rollers to a height such that a sealing nip between said pair of squeeze rollers is completely submerged under said upper surface of the developer liquid.
