Zusammenfassung:	A toner extruder for the preparation of a toner resin extrudate from a resin is provided. The extruder includes a housing defining a housing aperture and a resin inlet opening in the housing. The extruder also includes a conveyor for conveying the resin through the housing aperture. A lead-in gap at the resin inlet opening collects prematurely melted base resin and holds it for take-up by the conveyor, thus preventing fusing of the resin on the conveyor and avoiding clumping. The extruder can further include a member adjacent the resin inlet opening for inhibiting the heat transfer from the housing and/or the conveyor to the resin at the opening. The flow of resin adjacent the opening is thus improved.
