Disposable development station using two component developer and method of making same

摘要

A development station for developing electrostatic images includes a housing which has a vertically oriented separating wall which divides the housing into first and second chambers. In assembly both chambers are open at the top permitting ready loading of one chamber with a mixture of toner and carrier and the other chamber with substantially toner. The separating wall includes an opening at the bottom for passage of toner into the chamber containing the mixture. A toner applicator is located at the top of the chamber containing the mixture and a cover is permanently affixed across the tops of the chambers, totally sealing the chambers except for an opening in the cover opposite the toner-applicator. Because of the design of the station, especially the chambers which are open at the top for easy loading of toner and carrier, the station can economically be made disposable. A method for assembling the elements which make up the development station and for loading the toner and/or carrier in the various chambers is also described.
