Abstract:
1. A method of forming an image, which comprises: image-wise exposing a mono-sheet heat developable photosensitive material to laser diode light source having light intensity of not less than 1 mW/mm 2 at a wavelength of 350 nm to 430 nm, and heat-developing the exposed material at a temperature of from 110 to 150° C. by a heat-developing machine having an exposure section, a heat-development section and a cooling section, wherein a ratio of a zone length of the cooling section to a zone length of the heat-development section is not more than 3.5, wherein the mono-sheet heat developable photosensitive material comprises a support having a layer thereon containing: (a) a light-insensitive organic fatty acid silver salt including at least silver behenate having a specific surface area of not less than 10; (b) a light-sensitive silver halide that is prepared in the absence of the light-insensitive organic fatty acid silver salt and has an average silver iodide content of from 70 to 100 mole %; (c) a thermal developer; (d) an organic polyhalogen compound that is represented by the following formula (H): wherein Q represents an alkyl group, an aryl group or a heterocyclic group; Y represents a divalent connecting group; n represents 0 or 1; Z (e) a phthalazine compound; and (f) a binder, and wherein the photosensitive material exhibits substantially no light-sensitivity after being subjected to heat-development.
