Disclosed is a photographic processing composition in the tablet form which comprises a first and a second ingredients, said composition being prepared by a first granulating a first powder comprising said first ingredient to form first granules, a second granulating a second powder comprising said second ingredient to form second granules, mixing said first and second granules, and compressing said mixture of granules. The tables have an apparent density of 1.0 to 2.5 g/cm.sup.3.

Processing composition in the tablet form for silver halide photographic

A recycling method for photographic processing waste liquid is disclosed. The photographic processing waste liquid is subjected to evaporative concentration under a reduced pressure of not higher than 700 mmHg and at a temperature of not higher than 90.degree. C. The resulting distillate is used as a solvent for photographic processing agents or as an evaporation compensator for processing tanks of an automatic processing machine.

Recycling method for photographic processing waste liquid

In an apparatus for processing a light-sensitive silver halide photographic material, there is provided a solid agent replenishing device to store a package in which a solid agent is packed in a moistureproofing manner. The replenishing device releases the solid agent from the package so as to directly replenish the solid agents to the processing tank.

Automatic processing machine for silver halide photographic

A method for developing light-sensitive silver halide photographic materials, in a compact automatic developing machine, comprising transporting the light-sensitive silver halide photographic materials to a processing tank which contains a processing solution for processing an exposed light-sensitive silver halide photographic material. The processing tank includes a processing portion, and a receiving portion for receiving a solid processing agent. A solid processing agent is supplied to the receiving portion of the processing tank based on information on the amount of processing of the light-sensitive silver halide photographic materials. The solid processing agent is preferably in the form of tablets which contain all components necessary to process the light-sensitive silver halide photographic material. The processing solution is circulated between the processing portion and the receiving portion at a flow rate of not less than 0.5 times the processing tank volume per minute.

Method for automatically processing silver halide photographic

A solid developing composition for providing a color developer of a silver halide photographic light-sensitive material is disclosed, which comprises a compound represented by the following Formula (I), and a compound represented by the following Formula (II) or a saccharide: ##STR1##

Solid processing composition for silver halide photographic

An apparatus for processing a light-sensitive silver halide photographic material and which has a solid agent replenisher, is provided with a water producing device to recover water from the air or from used processing solution. The apparatus also is provided with a water replenisher which delivers recovered water to a processing tank to replenish the water in the processing solution contained therein.

Automatic developing machine for silver halide photographic

A method for processing a silver halide color photographic light-sensitive material is disclosed. Fogging caused by the color developer contaminated by heavy metal ions is surpressed by the processing method. The processing method is excellent in the point that stable photographic propertied can be obtained for long while of running. The processing method comprises a step for developing with a color developer an imagewise exposed light-sensitive material which comprises a support and a photographic layer being provided on the support and including at least one silver halide emulsion layer, wherein the photographic layer has a swelling ratio within the range of from 1.5 to 3.5 and the silver halide emulsion layer comprises a silver halide emulsion having a silver chloride content of not less than 90 mole %, and the developing step is performed for a time of not less than 90 seconds with a color developer containing a compound represented by the following Formula (1): ##STR1## wherein R.sub.1 and R.sub.2 are each a hydrogen atom or an alkyl group provided that R.sub.1 and R.sub.2 are not hydrogen atoms at the same time, and R.sub.1 and R.sub.2 may be combined to form a ring.
