Abstract A toner handling system having developing apparatus for developing a latent electrostatic image on a photoreceptor and a reclaiming system for reclaiming residual toner removed from the photoreceptor, has a novel reclaiming receptacle. The receptacle includes two openings, an unfiltered opening through which toner enters the receptacle during the reclaiming operation, and a filtered opening which is closed during this operation. When a predetermined amount of toner has been deposited in the receptacle, the latter is disconnected from the remainder of the reclaiming system, the unfiltered opening closed, and the filtered opening opened. The reclaimed toner is then poured through the filtered opening back into the developing apparatus, and the receptacles with any contaminant therein is discarded.
An improved toner handling system having means for developing a latent electrostatic image on a photoreceptor, and means for removing and reclaiming residual toner from the photoreceptor, the reclaiming means including a brush in contact with the photoreceptor and a receptacle into which the residual toner is deposited, wherein the improvement comprises: means forming a first unfiltered opening in the receptacle, means for conveying toner from the brush to the first unfiltered opening, means forming a second filtered opening in the receptacle, and means for closing the second filtered opening while residual toner is being deposited in the receptacle.
