Silver halide photographic material and method for developing the same

A method for forming an image from a silver halide photographic material comprising the steps of image-wise exposing a silver halide photographic material and developing the exposed silver halide photographic material, said silver halide photographic material comprising at least one sensitizing dye represented by formula (I):

• ##STR24## wherein V.sub.1, V.sub.2, V.sub.3, V.sub.4, V.sub.5 and V.sub.6 each represents a substituent satisfying the condition of:
• Y=.sigma.p1+.sigma.p2+.sigma.p3+.sigma.p4+.sigma.p5+.sigma.p6<-0.27, and Hammett's .sigma.p value of each being .sigma.pi with i being from 1 to 6;
• R.sub.1 and R.sub.2 may be the same or different and each represents an alkyl group;
• L.sub.1, L.sub.2, L.sub.3, L.sub.4, L.sub.5, L.sub.6 and L.sub.7 each represents a methine group, and m represents 0 or 1;
• Z represents an atomic group necessary for forming a 5-membered or 6-membered nitrogen-containing hetero ring;
• and
• X represents a charge balancing counter ion, and n has a value of at least 0 which is necessary for neutralizing the charge of the compound.
