ABSTRACT:
A developing device for the dry development of exposed photosensitive material, e.g. blueprint paper, by a gas or vapor developer comprises a housing formed with shielding chambers which prevent the escape of the vapor into the environment. According to the invention, a pair of shielding chambers are provided at the inlet and outlet sides of the developing chamber and each is subdivided, in the direction of movement of the sheet, into at least two compartments, preferably with flexible wall members which form a lip seal with a surface over which the sheet is intended to ride. The compartments are evacuated.
