摘要： A black and white photographic material is disclosed. The material contains a black image-forming coupler shown by formula (I) or (II) ##STR1## wherein R represents ##STR2## Y.sub.1 represents a group which prevents the coupler from diffusing away from the layer containing it. Examples of such groups include an aliphatic group, an aryl group, an aralkyl group, or a heterocyclic group. X.sub.1 and X.sub.2 each represents a hydrogen atom or a coupling-off group capable of being released upon oxidative coupling reaction with a developing agent. The material is capable of producing an excellent black image by development after image exposure. In the photographic material, the amount of silver can be effectively reduced and the photographic material give black images even after bleaching the black image formed.
