Two-color recording paper comprising an ink film and a thermosensitive recording paper which are separably mated together. The ink film has a thin film base and an ink layer of a first hue coated on the film base. The ink layer contains a mixture of a colored material such as dye with a thermoplastic material which is solid at ordinary temperature and becomes fluid at high temperature. The thermosensitive recording paper has a substrate and a coloring layer coated on the substrate. The coloring layer contains a developer which colors in a second hue different from the hue of the ink layer. The ink film and the thermosensitive recording paper are overlapped separably with an ink surface of the ink film and a coloring surface of the thermosensitive recording paper facing each other. The recording paper is fed at a predetermined feedrate to a first thermal head disposed on the paper path, which head melts ink of the ink film to form a transferred image, and the ink film is peeled from the thermosensitive recording paper to perform recording in the first hue. Recording in the second hue is carried out by coloring the thermosensitive recording paper by a second thermal head after correction regarding the scanning line has been completed.
