A standard color image and at least one processed image are printed on a single sheet of photosensitive material. The standard color image is obtained by carrying out standard image processing on a single original color image. The processed image is obtained by carrying out image processing under different processing conditions on the original color image. The different processing conditions may be the processing conditions for altering an image tone, image sharpness, image gradation, image trimming, an image size enlargement scale factor, or a combination of at least two of them. Various prints, which are obtained from image processings carried out by setting the processing conditions to various different processing conditions, can thus be seen easily.

Method and apparatus for forming photographic images

A rinsing water supply system for supplying water to a rinsing unit of a developing apparatus in which photosensitive materials are processed and rinsed. The water supply system includes a pipe having a water supply passage through which water is introduced into the rinsing unit from a water source, a solenoid valve for opening and closing the water supply passage, and signal lines arranged along and integrally with the pipe and adapted for transmitting signals for operating the solenoid valve. This arrangement eliminates the necessity for installation of a signal transmission line independently from the water supply passage, for the purpose of transmitting signals for operating the solenoid valve.

Water supply system for developing apparatus

In photographic processing apparatus for developing, bleaching-fixing and washing photographic materials, a predetermined quantity of fresh wash water is supplied into a washing tank every time a predetermined amount of the photographic materials have been washed. The fresh wash water is provided by deionizing city water and is reservoired in a replenisher tank. In order to detect a predetermined loss of the fresh wash water in the replenisher tank, a conductivity increasing material is dissolved in the fresh wash water in the replenisher tank when a predetermined quantity of the deionized water is supplied so as to electrically connect a pair of electrodes disposed at a predetermined depth of the replenisher tank. A sterilizer is mixed in the fresh wash water to prevent bacterial growth in the replenisher tank. The conductivity increasing material and the sterilizer are prepared as a predetermined dose of mixture necessary and sufficient for the predetermined quantity of deionized water supplied into the replenisher tank.

A method of processing a silver halide-containing photosenstitive material for color photography includes the silver-removing step in which silver which is formed by reduction in the color developing step is oxidized by a bleaching agent and further changed into a soluble silver complex by the action of a fixing agent. In this process, bleaching is carried out in both a bleaching bath and a bleach-fixing bath, and fixing is effected in the bleach-fixing bath. In the bleach-fixing bath, a stream of bleach-fixing solution is brought into contact with the emulsion coating surface of the color photosensitive material at a higher flow velocity than that of a stream of bleach-fixing solution which is circulated in the bath. The time for processing carried out in the bleaching bath is set so as to be shorter than the time for processing in a bleaching bath in a conventional method wherein removal of silver is effected by the combination of a bleaching bath and a fixing bath which involves no bleaching process, and also the total time for processing carried out in the bleaching and bleach-fixing baths is set so as to be shorter than the total time for processing in the bleaching and fixing baths in said conventional method. As bleaching and fixing agents, a ferric aminopolycarboxylic acid complex and a thiosulfate are particularly effectively employed, respectively.

A plurality of patrones accommodating films to be developed are housed in a magazine, and this magazine is connected to a developing system. A conveyor for consecutively feeding leaders connected to the tips of the films is provided in the magazine, and these leaders are fed one by one into the developing system, whereby all the films are automatically developed.

Film supplying apparatus

A film feeding apparatus for automatically feeding a negative film accommodated in a patrone to a developing machine includes: means for accommodating a multiplicity of magazines piled one upon another, each magazine accommodating a patrone; driving means for feeding the lowermost magazine among those accommodated in the accommodating means to a film receiving port of the developing machine; and means for retracting the magazine from the film receiving port so as to be discharged after the feed of the film has been completed, whereby the magazines are successively moved, and the films are thereby automatically fed to the developing machine.

An apparatus for heating a processing liquid has a heater for heating the processing liquid and a temperature sensor for detecting the temperature of the liquid. The heater and the sensor are housed in a protective housing made of a metal or a ceramic material. Since the heater and the temperature sensor are provided together in one unit, the mounting of the apparatus on a processing tank is facilitated. In addition, since the output of the temperature sensor changes in accordance with whether the liquid level of the processing liquid is above or below the position to the temperature sensor, it is also possible to detect the liquid level from the change in the output of the temperature sensor.

Apparatus for heating processing liquid

The efficiency of silver recovery from photographic processing solutions is improved by the installation of a silver recovery water tank between the fix or blix tank and the wash water tank, which is provided with a mechanism for maintaining the silver concentration of said recovery tank at a substantially constant value, said mechanism comprising a detecting means for measuring the amount of the photographic material treated by the processing line involved and a means to supply water thereto operatable by signal from said detecting means.
