Abstract

PURPOSE:To dispense with a memory mechanism at all at the time of multicolor recording, by setting the distance, between the heating point for ink in each recording part on and beyond a second recording part and the transfer point to a recording medium, to the length obtained by adding the distance between the heating point of a first recording part and the transfer point thereof to the distance between the transfer point of the first recording part and the transfer point of each recording part. CONSTITUTION:One of the inks simultaneously heated and melted at the heating points a1, a2 of a first recording part A and a second recording part B is fed by a distance s1 in the first recording part A to reach a transfer point b1 to be transferred to a recording sheet 1. At this time, the other ink simultaneously heated and melted in the second recording part B is present at the position the distance s1 away from the heating point a2 and the distance from said position to a transfer point b2 is equal to the distance (l) from the transfer point b1 of the first recording part A to the transfer point b2 of the second recordingf part B. Therefore, the molten ink in the second recording part B is superposed on the recording image transferred and recorded in the first recording part A when said recording image has moved to the transfer point b2 of the second recording part B.
