Oxa- and thiadiazole compounds substituted in the 2 and 5 positions with secondary amino groups are employed as photographic developing agents for exposed radiation-sensitive silver salts. The developing agents can be employed as components in developer compositions, as incorporated developing agents, and as developing agents in diffusion transfer processes.
