Claims (1)

[Claims for Utility Model Registration] It has a plurality of recording electrodes and a common electrode in contact with an energized ink sheet, the number of recording electrodes that are driven simultaneously is counted, and the energizing time is varied depending on the number of the counted driving recording electrodes. In an electric recording device that records characters and images on recording paper, a number of pulses are generated according to the gradation of the data to be recorded, and the strobe width of each pulse is based on the number of driving recording electrodes counted above for each gradation. 1. An energization recording device characterized by comprising a data conversion section that changes the data.
