Abstract
In a melt-type thermal transfer printing apparatus, an ink ribbon is brought into contact with a recording medium. A thermal head presses the ink ribbon. By controlling an electric power supplied to the thermal head, a melt or fusion area of ink is controlled so as to obtain a multi-gradational image on the recording medium. The recording medium is a porous surfaced medium having a multilayered porous layer containing numerous pores having a porous diameter in a range up to about 25 .mu.m.
