1. A heat development system of forming an image by exposing and heat developing a sheet-form heat developable light-sensitive material by using a heat development image-forming apparatus comprising a conveying member, a light-sensitive material-supplying member and an image exposure member, said heat developable light-sensitive material comprising a support and a light-sensitive layer comprising a binder, an organic silver salt, a reducing agent for a silver ion, and light-sensitive silver halide grains,wherein said conveying member conveys said heat developable light-sensitive material from said light-sensitive material-supplying member to said image exposure member at a conveying speed of 1 meter/minute to 5 meter/minute, said light-sensitive material contains said organic silver salt and said light-sensitive silver halide in the total amount of 1 g/m2 to 2 g/m2 in terms of Ag, said light-sensitive material further comprises:

  • a back layer including at least one layer in the opposite side of said light-sensitive layer; and

    an electrically conductive layer comprising a binder and at least one crystalline metal oxide selected from the group consisting of ZnO, TiO2, SnO2, Al2O3, SiO2, MgO, BaO, MoO3 and a composite oxide thereof, and said light-sensitive material has a lateral resistance under the environment of 25°

    C. and a relative humidity of 10% of not larger than 1011Ω
