Latest Patents
Among his latest innovations is the patent for a "Hybrid scavengeless development using ion charging." This apparatus and method enhance the toner charge level in a hybrid scavengeless development system. The system features a housing that defines a chamber storing a supply of developer material, including toner. A toner donor member is spaced from the surface and is adapted to transport toner to a region opposed from the surface. A magnetic roll conveys the developer material in the chamber of the housing onto a region of the donor member. A charging device ion charges the toner loaded on the region of the donor member, while an electrode member, spaced near the surface of the donor member and electrically biased by a power supply, detaches toner from the donor member to form a toner cloud for developing the latent image.
Another significant patent is for a "System for controlling the color of toner mixtures." This apparatus is designed for the preparation of a mixture of toner resin and a liquid colorant. It includes a toner extruder that conveys the resin and a colorant adder that integrates the colorant into the toner resin within the extruder to create the toner mixture.
