Abstract: For formation of a photographic image by development of a silver halide photographic material with an automatic developing machine, a certain period of time or not longer than 15 seconds is set as the time of the development step and a silver halide photographic material is used which, when developed for a period of one-half of said certain period of time after such an exposure that the exposed silver halide photographic material, when developed for said certain period of time, would give a value of (Dmax-fog).times.1/2, gives a value of (D-fog) having 70% or more of the value of (Dmax-fog).times.1/2. The silver halide photographic material comprises at least one of a combination of (1), (2) and (3) or (2) and (4): where: (1) represents a silver halide emulsion containing a water-soluble iridium salt; (2) represents a silver halide emulsion layer with a silver amount from 1 to 3.5 grams/m.sup.2 coated on one surface of said emulsion layer; (3) represents silver halide grains wherein the mean grain size is 1.

Abstract: A method of forming an image comprising exposing, developing and fixing a laser scanner-utilizable silver halide photographic material which has at least one silver halide emulsion layer sensitized spectrally in an infrared region on one side of a support, said silver halide photographic material containing in at least one layer located on the emulsion layer side one or more of an additive selected from among:(1) surface active agents having a solubility of 0.005 wt % or more at 30.degree. C. in a developer and a surface tension of 45 dyne/cm or less (measured at 30.degree. C. in a condition of 1.0 wt % aqueous solution), and(2) polymers represented by the following general formula (I), and having a molecular weight of from 2,000 to 500,000:--X).sub.x (Y).sub.

Abstract: A silver halide photosensitive material is described, comprising two or more monodisperse silver halide emulsions of different average grain size on a support, wherein at least one of the said monodisperse silver halide emulsions has an average grain size of at least 0.7 .mu.m, and at least one of the silver halide emulsions has a smaller average grain size than the other, the average grain size of the silver halide emulsion as a whole being within the range of from 0.33 to 0.54 .mu.m, with a coated silver weight of from 2.3 to 3.8 g/m.sup.2, and which contains a sensitizing dye represented by formula (I) ##STR1## wherein Z and Z.sub.1 each represents a group of non-metallic atoms forming a thiazole nucleus, a benzothiazole nucleus, or a benzoxazole nucleus; R.sub.0 represents an alkyl group having from 1 to 6 carbon atoms, an allyl group, or an aralkyl group; R and R.sub.1 each represents an alkyl group or an aryl group; L, L.sub.1, and L.sub.
