In an electrically conductive thermal recording device, for example, as shown in FIGS. 1 and 2, a plurality of stylus electrodes 1 corresponding to the number of pixels in the main scanning direction of the recording medium are used.
and a common electrode 2 that faces the plurality of stylus electrodes 1 with a small interval in the sub-scanning direction (direction perpendicular to the main-scanning direction). In the case of a type thermosensitive recording device, a resistive ink donor film 4 is brought into sliding contact with the recording head 3, and ink donors are placed between the stylus electrode 1 and the common electrode 2 according to the image information applied to the drive circuit 5. By applying electricity via the film 4, the energized portion of the ink donor film 4 is made to generate heat, thereby transferring ink to the non-thermosensitive recording paper 6 superimposed on the ink donor film 4 to perform recording. It's getting old. Further, FIG. 2 shows a case where a resistive thermosensitive recording paper 7 is used, and this recording paper 7 is directly energized to generate heat, thereby causing the recording paper 7 to develop color for recording.

キが発生し、画質を低下させてしまつていた。 By the way, in the conventional transfer-type or intuitive-type current-carrying thermal recording device as described above, since the resistance value of the ink donor film 4 or the thermal recording paper 7 varies partially, it is difficult to apply almost equal current from the stylus electrode 1. When the current flows, the amount of heat generated by the energization is not uniform, resulting in variations in recording density and deterioration of image quality.

Therefore, the present invention includes means for measuring the resistance value of the energized portion of the ink donor film or thermal recording paper, and energization from the stylus electrode based on the resistance value measured by the means, so that the heat generation of the energized portion is substantially reduced. The above object is achieved by providing a control means so that the temperature is uniform.
