Abstract
A thermal transfer type printing apparatus has a thermal head unit for selectively and thermally transferring an ink layer of an ink ribbon onto a paper sheet in response to printing information. The ink layer, in which blanks of ink corresponding to the printing information remain after printing, is heated and made molten by a heat roller, and the negative image formed by these ink blanks is thus rendered illegible.
