ABSTRACT:
To provide simultaneous and efficient mixing and blending of the toner and carrier components of a multicomponent developer, there is a hybrid crossmixer comprising an auger-type active section and a pair of baffle-type passive sections. The crossmixer is used, for example, in a magnetic brush development system on the downstream side of the development zone. In that event, the partially denuded developer exiting from the development zone is split, with approximately half being routed to the active section and the other half being more or less equally divided between the two passive sections. Furthermore, the additional toner needed from time-to-time to maintain the toner concentration of the developer at a suitably high level enters the system via the active section of the crossmixer to ensure that it is rapidly blended in with the balance of the developer.
