The present invention relates to a direct positive silver halide photosensitive material and a method for forming a direct positive image. By the use of a novel nucleating agent having a specific structural formula, the present invention provides a direct positive silver halide photosensitive material with an increased Dmax value and a decreased Dmin value, as compared with the use of the conventional nucleating agents, even if a small amount of the novel nucleating agent is used, and does not substantially reduce the Dmax value, even if the photosensitive material is kept in a high-humidity state for a long time before exposure.
