ABSTRACT:
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. The extruder further includes 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.
