摘要： In an image recording method comprising the steps of heating a sublimable dye to produce dye vapor, jetting the dye vapor from a nozzle toward a recording member, and attaching the dye vapor to the recording member to form a picture image thereon, the method of the present invention is adapted such that a gas stream is provided to pass across the stream of the dye vapor jetted from the nozzle and the dye vapor or fine particles of the sublimable dye formed by being cooled are taken away from the vicinity of the recording member by means of the gas stream.

摘要： Disclosed is an image recording method and its apparatus, in which dye vapor generated by heating sublimable dye is mixed with condensable vapor generated by heating condensable substance and formed into mixed vapor having higher pressure than the pressure outside a recording head and the mixed vapor thus formed and provided with a force to blow out by the pressure difference between inside and outside the recording head is adapted to jet from a nozzle with its jet amount controlled by control means, and according to which, high speed image recording is made possible although the temperature for heating the sublimable dye can be kept low, and the condensable vapor included in the mixed vapor is cooled while flying or upon reaching the surface of a recording member to reduce in volume, and therefore, the picture element is made smaller in diameter and spreading out of the jet around the nozzle along the surface of the recording member is prevented so that recording of high resolution is made possible.
