ABSTRACT:
In picture image forming apparatus employing a copying paper and a transfer printing ribbon with both ends connected to take up cores, when the leading end of the copying paper is located close to a transfer printing unit, the tension of the ink ribbon is increased for preventing clogging of the paper and misalignment of printed picture images. Further, the tensions applied to the both ends of the ribbon are controlled to apply a braking force to the ribbon and then stop the same for the purpose of preventing over running of the ribbon.
