Abstract

Disclosed is a process for cleaning toner bottles before they are refilled. A given weight of low quality carrier is dispensed into returned bottles. The bottles are agitated to develop a triboelectric charge that attracts residual toner particles adhering to the interior walls of the empty bottles. The carrier is emptied leaving a clean bottle ready for refilling. The toner is then removed from the carrier so the carrier can be reused. This is accomplished by passing the carrier against at least one conductive, rotating drum maintained at an appropriate electrical potential. An electrostatic force gradient between the carrier and the drum's surface attracts the toner particles. A cleaning blade thereafter strips the toner from the drum. This process yields cleaned carrier ready for reuse in bottle cleaning, and toner that can be recycled back to a toner production process.
