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.

Abstract: Most ribbon re-inking machines are not clean and convenient to use. The present machine is relatively clean to use because the ink reservoir is normally kept oriented so that leakage does not occur. Thus, the reservoir has an inlet which is sealed once ink has been added while an inking roller fits in an outlet on the same side as the inlet. Thus ink can only flow onto the roller when the reservoir and whole machine is inverted for use. An air inlet is provided on the other side of the reservoir from the outlet and roller and that inlet is opened when the reservoir is inverted. Only then will ink flow during rotation of the roller when a ribbon is moved over it.

Abstract: An electrostatic latent image residing on an electrically insulating surface used to induce a similar image on a sectionally conductive member by bringing one surface of the sectionally conductive member into proximity with the latent image while the opposite surface of the sectionally conductive member is brought to ground potential. The sectionally conductive member is then removed from proximity with the latent image.

A latent image is thus formed on the sectionally conductive member which can be developed by conventional means such as with electroscopic materials well known in the xerographic art.
