A transfer type xerographic machine employing a two component developer mix has two toner containers (80 and 81) in the developer station 25. One of these containers receives virgin toner, the other, toner collected by a cleaning station 38 from imaging element 12. The developer mix is replenished by toner from both containers simultaneously. A toner level monitoring system provides an indication of low level of virgin, but not used, toner. |
