A thermal transfer type printer head for transferring ink onto an article by heating ink to send it flying, wherein auxiliary walls are provided in supply passages adjacent to a transfer unit to raise ink liquid levels in the supply passages to thereby prevent running-out of ink in the supply passages. Accordingly, the transfer unit where ink has been consumed is spontaneously replenished with ink through the supply passages by means of capillarity, so that ink is continously supplied to the transfer unit without hindrance. Also, a section immediately above a heater provided on the transfer unit is constructed to prevent an amount of ink more than needed from entering thereinto. Accordingly, for example, even when the wettability of an ink holding construction formed above the heater is enhanced due to adhesion of substances which will cause thermal deterioration, a large amount of ink hardly enters above the heater to rapidly change the amount of ink transferred. |
