Abstract: In a process for forming an image by diffusion transfer, this process for forming an image comprises performing the diffusion transfer by using a hydroxylamine represented by the formula: ##STR1## as a developing agent, and using a cyclic imide as a silver halide solvent in the presence of a 1-aryl-3-pyrazolidinone compound represented by the formula: ##STR2##

Abstract: A method for bleaching silver halide color photographic materials is described using a bleach solution containing an organic acid metal complex salt and hydrogen peroxide or a compound releasing hydrogen peroxide, wherein the bleaching activity of the bleach solution can be effectively maintained for a long period of time by supplying thereto a replenisher composed separately of a composition containing hydrogen peroxide or a compound releasing hydrogen peroxide and a composition containing an organic acid metal complex salt, which are separately stored and added as a mixture thereof or separately to the bleach solution when the activity thereof is weakened during processing or during storage of the bleach solution.

Abstract: A bleach solution for color photographic materials having a high bleaching activity and capable of providing color images having good quality containing hydrogen peroxide or a compound releasing hydrogen peroxide, an organic metal complex salt, and an unsubstituted or substituted aromatic sulfonic acid or a salt thereof.

Abstract: A method which comprises processing an imagewise exposed and color developed silver halide color photographic material with a solution containing a ferric ion complex, a bromate and a water-soluble chloride is disclosed.

Abstract: A process for electrolytically regenerating a used bleaching-fixing solution resulting from the processing of a color developed color photographic material with a bleaching-fixing solution containing an iron (III) chelate compound and a silver halide solvent, which comprises bubbling an oxygen-containing gas into an anode compartment containing said used bleaching-fixing solution while electrolyzing said used bleaching-fixing solution in an electrolytic cell.

Abstract: A process for the recovery of silver from a fixing solution used in processing silver halide photographic light-sensitive materials wherein an electrolytic cell having a cathodic cell and an anodic cell separated by a diaphragm is used; silver is recovered from the used fixing solution in the cathodic cell and the anodic cell is filled with a fixing solution which has been used or not used in photographic processing, or an electrolyzed fixing solution.

Abstract: An electrolytic cell for recovering a metal from a solution has a diaphragm between a cathode and an anode. The diaphragm is supported by a support frame composed of a number of support columns. At least two of the support columns are made hollow in structure. A solution supply port is provided in at least one of the hollow support columns and a solution take-out port is provided in each of the remaining hollow support columns.

Abstract: A process for electrolyzing a bleach-fixed solution, or blix solution, used in processing color photographic materials, which contains originally an iron (III) chelate compound and a silver halide solvent in an electrolytic bath and separating the cathode compartment and the anode compartment of the electrolytic cell with a porous membrane and controlling the anode potential so that the silver halide solvent does not decompose. Embodiments include use of a carbon fiber as the anode and also controlling the cathode potential and the current densities of the cathode and the anode.
