Abstract
Disclosed is a method of developing a transmission black-and-white silver halide photographic material with an automatic processor, in which a developer having a bromide ion concentration of 0.01 mol/liter or less and having a pH value of 9.8 or less is used with replenishment of the developer being in an amount of about 200 ml or less per m.sup.2 of the material being processed. Though the amount of the replenisher to the developer used is small in the method, the photographic properties of the processed material are stable and the processed material is fogged little.
