Abstract: A direct positive type silver halide color photographic material and an image forming method are disclosed. A green sensitive emulsion layer of the photographic material comprises silver halide grains having at least two peaks on the size distribution curve thereof and the grain size corresponding to the smallest grain size peak among the peaks is not more than 0.3 .mu.m and a magenta coupler represented by the following Formula (M-I); ##STR1## wherein Z is a group of non-metal atoms necessary to complete a nitrogen-containing heterocyclic ring; X is a hydrogen atom or a split-off group and R is a substituent. The photographic material is developed with a color development in the presence of a fogging agent to directly form the positive image after imagewise exposure to light. Thus obtained image is improved in a increased maximum density, lowered minimum density and wider exposure latitude. Stability of gradation with respect to variation of development conditions is also improved.

Abstract: A direct positive silver halide photographic material with an internal latent image-type silver halide emulsion layer that provides a direct positive image by a fogging treatment (for example, an overall exposure, or surface developing treatment in the presence of a fogging agent) after imagewise exposure. The silver halide particles which form the emulsion layer consist essentially of a core portion made of silver halide and having been chemically sensitized or doped with metal ions. There are provided a plural number of shell portions made of silver halide containing silver chloride. The chloride content of an inner shell adjacent to the outmost shell of the particles has a smaller amount of chloride content than that of the outermost shell. The photographic material is used by first imagewise exposing it to light, effecting overall fogging treatment on the silver halide particles and processing the exposed photographic material to produce the image.
