ABSTRACT:
In the transfer of a toner image from a transfer medium such as a belt to transfer material such as paper, heating and fixing of the toner is required. According to the present invention, two sources of heat are used, one applied to the transfer medium and the other to the paper, the heat applied to the transfer medium being insufficient to melt or fuse the toner, with the heat applied to the paper being greater than necessary for fusing. When the hot paper contacts the underheated transfer medium the temperature of the latter is then and only then increased to the fusing temperature and the transfer and fixing of the toner image upon the paper takes place.
