  • Publication number: 20060067683
    Abstract: A photo-finishing apparatus for a silver halide photosensitive material, including an agitating device to agitate or circulate a processing solution in a processing tank, a time detecting device to detect an elapsed time since a processing operation was completed, a temperature detecting device to detect temperature of the processing solution in the processing tank, and a control section to control operation of the agitating device by such ways that when the time detecting device detects a predetermined elapsed time, the control section deactivates the agitating device, and when the temperature detecting device detects that the temperature of the processing solution in the processing tank has dropped lower than a predetermined lower limit temperature, the control section re-activates the agitating device, and continues to activate until the temperature detecting device detects that the temperature of the processing solution in the processing tank has increased to a predetermined acceptable processing temperat

  • Patent number: 4908300
    Abstract: A method of a processing of a silver halide color photographic material is disclosed. The process comprises a step of developing the exposed color photographic material and a step of treating the developed color photographic material with a bleach-fixing solution. The bleach-fixing solution contains an organic acid ferric complex. At least one layer of the emulsion layers of the photographic material contains silver halide grains containing from 0.5 to 25 mol % of silver iodide. The total dry-thickness of the photographic component layers contained in the photographic material is from 8 to 25 .mu.m and the swelling rate T1/2 of the photographic component layers is not more than 25 sec. The method is suitable for rapid processing of the fine grain-type high-speed silver iodide-containing color photographic material. The method uses a bleach-fixing bath enabling the rapid processing of the high-speed color photographic material.
