Photographic processing composition and image-forming method using the same

A photographic processing composition, comprising at least one compound selected from the group consisting of a compound represented by formula (I) and a compound represented by formula (II):

• A1-X-L-Y-A2 (I)
• wherein, in formula (I), A1 and A2 each independently represent an aryl group or an aromatic heterocyclic group, in which A1 and A2 do not include a triazinyl group;
• L represents an arylene group or a divalent aromatic heterocyclic group, in which L does not include a triazinylene group;
• X and Y each independently represent a divalent linking group;
• the compound represented by formula (I) contains at least two of a group represented by —SO3M or —CO2M;
• M represents a hydrogen atom, an alkali metal, an alkali earth metal, an ammonium or a pyridinium;
• a molecule represented by the formula (I) does not contain a group represented by —N═N— or —SH;
• and when L is a divalent aromatic heterocyclic group, X and Y each do not represent a divalent linking group singly composed of N(R1), S or O, in which R1 represents a hydrogen atom, or an alkyl group having 1 to 6 carbon atoms;
• wherein, in formula (II), A11 represents a tri- or tetra-valent aromatic hydrocarbon group or a tri- or tetra-valent aromatic heterocyclic group, in which A11 is not a trivalent group of triazine;
• A12 represents an aryl group or an aromatic heterocyclic group;
• X1 represents a divalent linking group;
• M1 represents a hydrogen atom, an alkali metal, an alkali earth metal, an ammonium or a pyridinium;
• a molecule represented by the formula (II) does not contain a group represented by —N═N— or —SH;
• n is an integer of 3 or 4;
• and r and s each are an integer of 0 to 10, in which r+s is 2 or more.
