Abstract
Abstract An ink-jet recording method where the heat emitting body is always maintained at a temperature higher than the ink vaporization temperature and where ink is transported onto the heat emitting body only at the time of printing. The printing speed of the ink-jet printer realized is controlled not by the heat response speed of the heat emitting body but by the speed at which ink can be moved. Further, the ink-jet recording method can control the rate at which ink is ejected onto the recording paper by controlling the rate at which ink is transported onto the heat emitting body. Therefore, the intensity of printing can be controlled.
