となる。 In addition to the conventional thermal transfer recording method, a transfer master in which a pigment or dye is used as a colorant dispersed in a binder, or a pigment or dye is directly used as a thermal transfer layer, and these are provided on a support is used. From the support side, the transfer layer is melted according to the recorded signal using a heating means such as a hot pen or a thermal head, or a means that uses light such as a laser beam to perform light-to-heat conversion by light absorption of the thermal transfer layer. , depositing a colored thermal transfer material by sublimation or evaporation onto plain paper that is placed in close contact with the transfer layer;
There is a method of recording on plain paper according to image signals. In this method, the amount of transfer material to be transferred is determined by the difference in adhesive strength between the transfer material and the receiver, and the adhesive strength between the transfer master support and the transfer material. Uneven adhesion directly causes uneven transfer amount, that is, uneven density.

Differences in the amount of transfer of the transfer layer occur due to differences in magnitude of the three forces consisting of Fc. That is, Fa 1 −Fa 2 −Fc
In this case, only a part of the transfer layer is transferred as shown in part A of FIG. When Fa 1 , Fc>Fa 2 , no transcription occurs at all, as shown in FIG. 1-B.
When Fa 2 , > Fa 1 , Fc, 100% of the transfer layer is transferred to the receiver, as shown in FIG. 1-C. The difference in transfer effect as described above is the cause of density unevenness.
