  • Method of fixing a toner powder image on a sheet of material
    Patent number: 4094674
    Abstract: A method of fixing a toner powder image on a sheet of material. A substantially flat impact surface is provided, and the side of a sheet opposite to the side carrying a freshly applied toner powder image is placed into contact with the flat impact surface. The surface of the sheet of material carrying the toner powder image is impacted by a plurality of pellets, each of which has an impacting area which is substantially smaller than the area of the surface of the sheet of material carrying the toner powder image. The pellets are preferably repeatedly impacted against the sheet of material and in a random manner to achieve pressure fixing of the entire surface of the sheet of material.
