PURPOSE:To always obtain stable printing by polishing the recording surface of a recording head simultaneously with the scanning of an electrical heat generating sheet, in the electrical heat generating sheet of the electrical thermal transfer apparatus, by containing fine hard particle in the contact surface with the recording head of said sheet. CONSTITUTION:A proper amount of fine alumina particles 20 usually used as a polishing material are mixed and disperesed in the current conductive layer 2 of a current supply heat generating sheet 1 consisting of a conductive layer 2, a support layer 3 and a heat-fusible ink layer 4. By this method, the recording surface of the head is polished simultaneously with printing through the scanning of the electrical heat generating sheet and the contactness of the conductive layer 2 and a recording electrode can be held well. |
