A method for forming an image which comprises processing a silver halide photographic material having provided on a support at least one silver halide emulsion layer which comprises silver halide grains containing a silver chloride of 50 mol % or more and at least one emulsion layer and other hydrophilic colloid layers contain at least one hydrazine derivative represented by formula (I) and at least one phosphonium salt compound represented by formula (II), is processed with a developer having a pH of from 9.0 to 11.0, ##STR21## wherein R.sub.1 is a group represented by formula (Ia), (Ib), (Ic), (Id) or (Ie) ##STR22## wherein L.sub.1, L.sub.2, and L.sub.3, may be the same or different and each represents --CONR.sub.7 --, --NR.sub.7 CONR.sub.8 --, --SO.sub.2 NR.sub.7 -- or --NR.sub.7 SO.sub.2 NR.sub.8 --;
- R.sub.7 and R.sub.8 each represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or an aryl group having from 6 to 10 carbon atoms;
- m and p each represents 0 or 1;
- R.sub.3 and R.sub.4 each represents a divalent aliphatic or aromatic group, R.sub.5 represents an aliphatic group, aromatic group or a combined group thereof;
- Z.sub.1 represents an aromatic group necessary for forming a nitrogen-containing aromatic ring;
- R.sub.6 represents an aliphatic group or an aromatic group;
- L.sub.3 represents --CH.sub.2 CH.sub.2 O--, --CH.sub.2 CH(CH.sub.3)O-- or --CH.sub.2 CH.sub.2 (OH)CH.sub.2 O--;
- X represents a counter ion;
- in which n is an integer of 3 or more, G.sub.1 represents --CO--, --COCO--, --CS--, --C(=NG.sub.2 R.sub.2)--, --SO--, --SO.sub.2 --, or --P(O)(G.sub.2 R.sub.2)--;
- G.sub.2 represents a chemical bond, --O--, --S--, or --N(R.sub.2)--;
- R.sub.2 represents an aliphatic group, an aromatic group, an amino group, or a hydrogen atom, and plural R.sub.2 's, may be the same or different;
- and, one of A.sub.1 and A.sub.2 is a hydrogen atom, while the other represents a hydrogen atom, an acyl group, or an alkyl- or arylsulfonyl group;
- ##STR23## wherein R.sub.21, R.sub.22 and R.sub.23 each represents an alkyl group, a cycloalkyl group, an aryl group, an alkenyl group, a cycloalkenyl group or a heterocyclic group m represents 1 or 2;
- L represents an m-valent organic group bonded to P atom in the formula via its carbon atom;
- n represents an integer of from 1 to 3;
- and X represents an n-valent anion, and X may be linked to L.
