PURPOSE:To eliminate stably a visible image of a recording medium by a method wherein a device to be driven by a plurality of electrification pulse rows, which are generated within an image dot forming cycle of a recording unit of a visible image and has pulse cycles different from each other, is provided. CONSTITUTION:Pulse data for formation of an electrification pulse row recording/eliminating a visible image being stored within a driving pullse data ROM 18 is transferred to a driving pulse forming part 19 from the driving pulse data ROM 18. With this construction, the electrification pulse row for driving a thermal head 21 is formed and sent to a thermal head driving part 20. In the thermal head driving part 20, since an original image data, a corrected recording/eliminating energy data and the formed electrification pulse row are supplied respectively, they are converted into signals driving the thermal head 21 and supplied to a thermal head 26. The thermal head 21 performs recording/eliminating actions of the visible image in accordance with the image data. |
