ABSTRACT:
Non-magnetic and non-conductive powdered toner is applied to a rotating image cylinder having an electrostatic pattern. A container having a closed bottom and sides and open top contains the powdered toner. The powder is fluidized by introducing air through a pervious closed bottom of the container, and by vibrating the container. The toner is simultaneously stirred and electrically charged to a potential of greater than about 7 kv (plus or minus polarity) by rotating elements with radial pointed appendages in the container. Toner is transferred from the container to an image cylinder at an exposed nine o'clock position of the image cylinder by a plurality of transfer cylinders. A first transfer cylinder is mounted so that its periphery is just above the open top of the container and an applicator cylinder has its axis below the axis of the first cylinder, and its periphery adjacent both the first cylinder and the image cylinder. A second cylinder is for the removal of opposite sign charged toner and low charge toner from the applicator cylinder. Scrapers scrape unused toner from the first and applicator cylinders so that it falls into the open top of the container.
