Toner recovery, cleaner and recirculator for copiers, printers and facsimile devices - subjects toners and impurities to electric field to separate toner according to particle size and charge

摘要

The image generating equipment has a latent electrostatic image developed by use of toner for printing, and a cleaner unit (11) collecting toner, passing it by an electrostatic agitator (13) along a route (12) to the developer unit (5). Along the route the toner and impurities such as paper dust is subject to electric fields to separate toner from impurities on the criteria of density, particle size and weight.
