Method and apparatus to heat fix a heat fusible xerographic powder image to a final support material in which the powder image is first transferred to a final support material and the image-bearing support material then brought into contact with a bath of hot liquid metal for a period of time sufficient to fix the image to the support material. The temperature of the bath is maintained at a temperature high enough to fuse the image but below that at which the support material is damaged. The liquid metal bath has floating on it a layer of molten non-metal to prevent oxidating of the metal and to precoat the support material on its entry into the bath to prevent particles of the liquid metal from embedding in the support material. The relative high density of the molten metal acts as a wringer to keep the plasticized coating very thin when drawn out of the bath.
A method of heat fixing a heat fusible xerographic toner image to a final support material to which it has been applied in image configuration, including:
A method of making an electrostatically reproduced copy wherein thermo-responsive particulate material is arranged in a predetermined pattern on a support material, including:
A method of fixing a heat fusible particulate material to a support material to which it has been applied in imagewise configuration, and of coating said support material said configuration of particulate material with a nonmetallic plasticizer, including:
