Abstract
In an electrothermal printing apparatus, ink ribbon is fed in a predetermined direction and is contacted with a recording electrode and a return electrode which is located upstream of the predetermined direction with respect to the recording electrode. A signal current is supplied from the recording electrode to a conductive layer of the ink ribbon through a resistive layer and the signal current supplied to the conductive layer is supplied to the return electrode through the resistive layer. Heat is generated at a portion of the ink ribbon, which is contacted with the recording electrode and is applied to the ink layer through the conductive layer, thereby printing an ink of the ink layer to a paper.
