PURPOSE:To perform the density gradation of transfer density, by a method wherein transfer operation is performed while a transfer ribbon and receiving paper are fed and the transfer pitch before feed quantity reaches predetermined one many times the width of a heat generating resistor in the feed direction of the receiving paper is set to a reference dot to control the current supply time within said reference dot. CONSTITUTION:The feed of a color transfer ribbon 1 and that of receiving paper 5 by a platen roller 7 are made continuous during the time from the start of printing to the finish thereof and the predetermined feed quantity corresponding to the width L of a reference dot D in a non-line direction is set to one transfer pitch to control the heat generating time (t) within the predetermined time To before said feed quantity is finished. That is, an LXW area is set to the area of the reference dot D, and the color transfer ribbon 1 and the receiving paper 5 are fed by L in the direction shown by an arrow S1. This feed time is set to To and, when a current is continuously supplied to a heat generating body 30 until reaching the time To, the size of the transfer dot on the receiving paper 5 becomes that of the reference dot D. |
