交換頻度を低減することができる。FIG. 2 shows a general thermal transfer printer, in which 10 volumes of image-receiving paper are conveyed in a fixed direction at a speed Vp by a platen roller lot, and n times used to be conveyed in the same direction at a speed Vi by a feed roller 103. Possible Inksey}-104
Superimpose. These receiving paper 102 and ink sheet 1
-104 is sandwiched between the platen roller 101 and the thermal head 105 that generates a thermal pattern according to the image recording information, and the image information is transferred to the image receiving paper +02 by selectively transferring the ink on the ink sheet +04. By setting the transport speed ratio V p /V i between the image receiving paper 102 and the ink sheet 104 to 1 or more, the ink sheet 104 can be used with high density and the frequency of replacement can be reduced. can.

影響する。By the way, such a printer is manufactured by, for example, Japanese Patent Application Laid-Open No. 57-8
As disclosed in Japanese Patent Publication No. 347-1 and Japanese Patent Publication No. 62-589-17, it is generally known that image density is influenced by the conveying speed Vi of the ink sheet. That is, when the ink sheet conveying speed ■l is Vi=V±Δ■, the speed ■ influences the absolute density, and the speed unevenness ΔV influences the density unevenness.

良好としている。On the other hand, the method disclosed in the above-mentioned Japanese Patent Publication No. 62-589 17 focuses on the fact that the speed V fluctuates depending on the winding diameter of the ink sheet and that the speed unevenness ΔV occurs due to rotational unevenness. By detecting the diameter and controlling the rotational speed according to this detection, the speed (2) is kept constant and the image density is made good.

を備えたことを特徴とする熱転写式プリンタ。(1) An ink sheet that can be used multiple times, which is transported in a certain direction from the ink sheet take-up shaft by a roller-type transport mechanism, and an image-receiving paper, which is transported in the same direction by another transport mechanism, are overlapped to form an image. A thermal transfer printer that transfers image information to image receiving paper by selectively transferring ink on the ink sheet using a thermal head that generates a thermal pattern according to recorded information, wherein the conveying mechanism controls the ink sheet conveying speed. The respective speeds are set so that the speed ratio Vp/Vi is 1 or more when Vi is the transport speed of the image receiving paper and Vp is the transport speed of the image receiving paper. What is claimed is: 1. A thermal transfer printer, comprising: a applying means for applying a liquid, and a control means for controlling the applying means to drive the applying means before starting printing.
