    (54) Process for forming a colour positive image


    (57) Disclosed is an internal latent image type light-sensi­tive silver halide photographic material capable of forming a color positive image by effecting surface development processing after fogging was carried out, and/or while fogging is carried out, with use of a color developing solution containing 1 g/liter or less of a solvent having a log P of 0.4 or more, having a sulfite ion concentration of 2 × 10⁻² mole or less per liter of the color developing solution and having a bromide ion concentration of 5 × 10⁻³ mole or less per liter of the color developing solution, wherein a silver halide grain contained in at least one layer of photographic consti­tuent layers of the light-sensitive material comprises a core and at least one layer of a shell covering the core, and the shell contains at least silver chloride as its surface composition, and also disclosed is an internal latent image type light-sensitive silver halide photogra­phic material which further comprises containing a heterocyclic mercapto compound.
