ABSTRACT:
In an apparatus for producing from a developer solution a gaseous developer medium for diazotype materials, which apparatus includes an inclined surface for passing the developer solution through a vaporizing region from a first end to a second end thereof, heater elements disposed along the vaporizing region, the temperature in the region of the second end being at least 25.degree. C higher than the temperature in the region of the first end and the temperature increasing with the distance from the first end, and a sipon at the second end for collecting the condensate of the vaporized solution. The siphon has a heater element for heating the solution collected therein to the temperature prevailing in the region of the second end to release more gaseous developer medium before the solution leaves the vaporizing region.
