A copier capable of producing both color images and monochrome images is disclosed, which comprises a platen for mounting thereon a manuscript, a scanner unit adapted to reciprocate relative to the platen and generate image signals divided in three primary colors by reading the manuscript for each line or for each set of a plurality of lines, four thermal heads for receiving image signals and, in response thereto, selectively actuating heat generation elements, means for supplying the thermal heads with ink donor films of four colors including black, and means for effecting thermal transfer printing on record paper.

A thermo-sensitive recording apparatus individually controls the energization level of each of a plurality of heater elements formed on a substrate and constituting a thermal print head. In generating each energization level, the present and previous status of an individual heater element and selected neighboring elements are taken into consideration. Other factors combined in a selectively weighted manner include the latent heat of the individual heater element and its neighboring heater elements, the resistance of the heater element, the percentage of heater elements to be activated during the printing of a line, and the temperature of the substrate.
