Abstract
A toner replenishment apparatus for a dry electrophotographic (EP) printer includes a rotatable transport subsystem in the developer. The subsystem includes an elongated housing with a feed port and various apertures arranged along its length. A channel within the housing receives toner from the toner supply through the feed port. A toner transport member in the channel moves toner received through the feed port to the apertures, and a developer-mixing member attached to the outside of the housing mixes toner and carrier particles in the developer. The toner transport member is stationary or rotates at a different angular velocity than the housing. When the rotation of the transport subsystem brings a selected one of the apertures below the center of the housing, toner passes through the selected aperture into the developer in the sump, and is mixed into the developer by the developer-mixing member as the transport subsystem rotates.
