Diaminostilbene series compound and a method for forming an image using the same

A method for forming an image, in which method, after a silver halide photographic material having a photosensitive silver halide emulsion layer on at least one side of a support is exposed to light imagewise, the silver halide photographic material is subjected to a developing step, a desilvering step, a washing and/or stabilizing step, and then the material is dried, which comprises at least one step of the above processing steps being carried out in the presence of at least one compound represented by the following formula (I):

• ##STR65## wherein L.sup.1 and L.sup.2, which are the same or different, each represent --OR.sup.1 or --N--R.sup.2 (R.sup.3), wherein the four substituents L.sup.1 and L.sup.2 have four or more substituents in total selected from the group consisting of substituents represented by the following formula (II);
• R.sup.1 and R.sup.2 each represent a hydrogen atom, an alkyl group, or an alkyl group having a substituent selected from the group consisting of substituents represented by the following formula (II);
• R.sup.3 represents an alkyl group or an alkyl group having a substituent selected from the group consisting of substituents represented by the following formula (II);
• and
• M represents a hydrogen atom, an alkali metal, an ammonium, or a pyridinium:
• formula (II)
• --SO.sub.3 M, --OSO.sub.3 M, --COOM, and --NR.sub.3 X
• wherein
• X represents a halogen atom,
• R represents an alkyl group, and
• M has the same meaning as M in formula (I).
