    摘要: Image recording is indirectly achieved on a recording sheet via an intermediate transferring medium. First, the circumferential surface of a rotatable transferring medium having heat-transferable ink contained therein is fused or softened in response to image information by means of a recording electrode which is disposed at the position opposite to the transferring medium while the intermediate transferring medium is interposed therebetween. After completion of the first transferring step the ink image which has been transferred onto the intermediate transferring medium is transported to the position where a second transferring step is achieved while the ink image is kept in the fused or softened state. The second transferring step is achieved in such a manner that the ink image is transferred onto the recording sheet under the effect of pressure which is imparted by a pressure roller. The intermediate transferring medium may be made of electric conductive material. Intermediate treatment such as removal of the ink image, partial correction of the same, addition of another ink image can be carried out between the first transferring step and second transferring step.
