Cleaning device, cleaning device for developing processing apparatus, drying device, and drying device for developing processing apparatus

A drying device for drying a sheet material having one surface wetter than the other, comprising:

• a hot air discharging means for blowing hot air onto the sheet material provided at the wetter surface side of the sheet material;
• a belt provided along the transporting direction of said sheet material at the other less wet surface side of said sheet material;
• and
• a transporting means for transporting the sheet material in a predetermined direction by moving said belt in the sheet material transporting direction.

A drying device to be used in a developing processing apparatus for heat development of a silver halide photosensitive material where an image is exposed and a processing sheet containing a chemical for forming an image on the silver halide photosensitive material in the presence of a solvent for image formation, comprising:

• a cleaning means for cleaning at least the heat developed surface of said silver halide photosensitive material after the heat development;
• and
• a drying means for drying mainly the heat developed surface of the silver halide photosensitive material moistened by cleaning by said cleaning means, wherein
• said drying means comprises a hot air discharging means provided at the wetter heat developed surface side of said silver halide photosensitive material moistened by cleaning by said cleaning means for blowing hot air to the silver halide photosensitive material,
• a belt provided along the transporting direction of said silver halide photosensitive material at the other non-heat developed less wet surface side of said silver halide photosensitive material, and
• a transporting means for transporting said silver halide photosensitive material in a predetermined direction by moving said belt in the silver halide photosensitive material transporting direction while supporting the non-heat developed surface of the silver halide photosensitive material.

A cleaning device for cleaning one side of a sheet material, comprising:

• a transporting means for transporting the sheet material substantially horizontally;
• a saucer for storing a cleaning liquid;
• a cleaning roller stored in said saucer, with the part lower than the rotation axis partially soaked in the cleaning liquid;
• guiding members arranged respectively on the upstream side and the downstream side with respect to said cleaning roller for guiding the sheet material transported by said transporting means such that it contacts with said cleaning roller at the uppermost point thereof, and
• a driving means for rotating said cleaning roller at an extremely high linear velocity with respect to the transporting rate of the sheet material by said transporting means for taking out the cleaning liquid by the roller surface such that a swirling flow for cleaning is generated in front of the contacting portion at said uppermost point,
• wherein said saucer comprises a member having a high heat conductivity so that the cleaning liquid can be heated or the warmth thereof can be kept by heating the saucer itself.
