ABSTRACT:
An apparatus for drying a photosensitive material in the form of a web is provided wherein a slender box-shaped housing defines an interior space having a rectangular slit-shaped transverse cross section in which its thickness dimension is substantially smaller than its transverse dimension. A fan is connected to the housing through a nozzle for blowing drying air into the interior space to dry the photosensitive web while the web is transferred through the interior space in a longitudinal direction. The difference in relative humidity between upstream and downstream air flows in the interior space at the beginning and the end of drying is controlled to at least 30% RH.
