ABSTRACT:
A method for processing a silver halide photographic material for infrared laser scanner is described, comprising developing the silver halide photographic material which comprises a support having thereon at least one hydrophilic colloidal layer including at least one silver halide emulsion layer with an automatic developing machine, wherein the silver halide emulsion layer contains silver chloroiodobromide grains having a silver iodide content of 0 to 2 mol% and a silver chloride content of 0 to 30 mol%, the hydrophilic colloidal layer has a swelling percentage of 200% or less, and as a developing solution for the development step in the automatic developing machine, a single developing solution containing a 3-pyrazolidone developing agent represented by formula (I) is used therein: ##STR1## wherein R.sub.0 represents a substituted or unsubstituted aryl group; and R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group, with the proviso that when R.sub.0 represents an unsubstituted phenyl group, at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group.
