A process for forming a high contrast negative image by developing an exposed substantial surface latent image type silver halide photographic light-sensitive material in the presence of hydrazines, which comprises using a developing solution having a pH value of 10.5 to 12.3 and containing at least (1) a developing agent, (2) 0.25 mol/l or more of sulfite, and (3) a compound represented by the following general formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5, which may be the same or different, each represents a hydrogen atom, a hydroxyl group, an alkyl group, an alkoxy group or a substituted alkyl group. According to the process, the development processing time required is shortened in the case of forming a high contrast negative image with a stable developing solution using hydrazines.
