Abstract:
1. An image forming method comprising steps of: providing a thermal transfer film comprising a coloring layer formed on a substrate film via an intermediate layer, wherein the intermediate layer is not transferable from the substrate and contains a thermally fusible substance an non-transferable binder resin, the melt viscosity of the thermally fusible substance in the temperature range 15 to 25° C. higher than the fuse peak temperature defined in JIS K7121-1987 of the thermally fusible substance is 100 mPa·s or more and 1000 mPa·s or less, the fuse peak temperature defined in JIS-K7121-1987 of the thermally fusible substance is in the range of 50 to 110° C., and the crystallization peak temperature defined in JIS K7121-1987 of the thermally fusible substance is in the range of −20 to 100° C., and the crystallization peak temperature of the thermally fusible substance is lower than the fuse peak temperature by 10° C. or more and the softening temperature of the binder resin measured by the ring and ball method defined in the JIS K2207-1980 is 130° C. or more and 400° C. or less; providing a transfer receiving material; superimposing the transfer receiving material on a coloring layer side of the thermal transfer film; heating and recording from the substrate film side according to the pixel by pixel heating means and separating the thermal transfer film and the transfer receiving material, whrein a time interval between recording each pixel and separating the thermal transfer film and the transfer receiving material as 2 seconds or less.
