A direct positive photographic material having a support and a silver halide emulsion layer thereon contains internal latent image type silver halide grains. These grains have a core/shell structure and have not been previously fogged. Each grain comprises a conversion type silver halide core and a silver halide shell over the core.The layer would produce, when exposed for a given time upto one second and developed at 20.degree. C. for 4 minutes with a certain internal developing solution, a maximum density which is at least five times that obtained when the layer is similarly exposed and developed with a particular surface developing solution.
