PURPOSE:To enable a quick developing process and to prevent the contamination of an unexposed part by using a specific color developing agent and using a specific bleaching accelerator. CONSTITUTION:The color developing soln. contains at least one kind of a p- phenylene diamine color developing agent having at least one alkyl sulfon amide alkyl group on a benzene ring and/or amino group. A solvent is incorporated into the color developing soln. in the volumetric ratio range expressed by [volume of (the solvent having <0.4 logP)]/[volume of (water) + (solvent having <0.4 logP except water)] <= 0.003. A soln. prepd. by using the ferric complex salt of an org. acid and thiosulfate as essential components is used for a bleach fixer and an org. acid such as aminopolycarboxylic acid or oxalic acid, citric acid, etc., coordinated with ion ions is used for a bleaching agent. |
