    (54) Image forming process


    (57) An image is formed in a silver halide photosensitive material by imagewise exposing it using a semiconductor laser or LD of the longitudinal single mode. The photosensitive layer has a γ value of at least 1.5 and optionally, a dynamic range of up to 2.0 as expressed in logE unit. The emission wavelength during exposure is in such a range that the Δlog(spectral sensitivity) of the photosensitive layer per nm is within ±0.015 and/or in a range of ±10 nm from the maximum spectral sensitivity wavelength (nm) of the photosensitive layer. An image of quality is obtained without image unevenness.
