Abstract
Using a thermal transfer recording medium formed with thermal transfer recording material on a surface of a supporting material, of which dynamic shear modulus of elasticity is within a range of 1.times.10.sup.3 Pa to 8.times.10.sup.5 Pa, and loss tangent tan .delta. is within a range of 0.6 to 2.5 measured in dynamic viscoelasticity measurement in a temperature range of the melting point thereof to 50.degree. C. over the melting point at a frequency of 0.5 Hz, pressurizing the heat generating elements against the thermal transfer recording medium to bring the same into contact therewith with a load of 0.3 to 1.0 N/mm, which is a load per unit length in the main direction of the arrangement of the heat generating elements, transferring the thermal transfer recording material to the printing medium.
