PURPOSE:To provide a transfer-type thermal printer capable of transferring ink even to paper of less smoothness by transferring to an object to be transferred beforehand that portion of ink not required for image formation on an ink sheet and then obtaining a required image through the transfer or residual ink on said sheet to a transfer paper. CONSTITUTION:The portion not requiring ink is heated and then is transferred to the reverse of a used ink ribbon. Consequently, a character pattern is formed on an ink ribbon 6 which has already passed through a thermal head. After this, the ink ribbon 6 reaches a pressure roller 7 to be pressed against transfer paper 5. Ink containing paraffin wax as a main component flows into the uneven part of the transfer paper 5 under the pressure of the pressure roller 7 to realize the transfer. At that time, if the pressure roller is heated nearly to an ink melting point using a heater, the transfer rate improves. The ink ribbon 6 which has finished transfer reaches an ink ribbon supply roller 8 again and then is overlapped with an unused ink ribbon. Following this process, the unrequired ink is received and later is recovered into an ink ribbon winding roller 9. |
