1. A thermo-sensitive recording apparatus in which thermal recording is made on successive lines of a medium under the control of selective energization of a plurality of heater elements formed in a substrate and constituting a thermal head, the apparatus comprising:

  • heat storage correction data forming means for generating latent heat correction data corresponding to the quantity of latent heat energy stored in each of the heater elements;

    a thermal history correction data forming means for generating thermal history correction data for each of the heater elements in accordance with the state of the elements during printing of a selected number of preceding print lines;

    a heater element resistance value correction data forming means for generating resistance data for each of the heater elements corresponding to the actual resistance of the heater elements;

    a black percentage correction data forming means for forming solid image correction data for energy to be applied to the thermal head in accordance with the number of heater elements to be energized during printing of a print;

    substrate temperature correction data forming means for forming substrate correction data corresponding to the temperature of the substrate; and

    applied energy control means for individually controlling energization of the heater elements in accordance with said latent heat correction data, said thermal history correction data, said resistance data, said solid image correction data, and said substrate correction data.
