Abstract: Disclosed is a device for mixing and/or conveying, in particular for mixing and conveying a developer composition in an electrophotographic copying machine. The device comprises an elongated member which is rotatable about its longitudinal axis, this member comprising a T-shaped lateral cross-section which has been spirally twisted about its longitudinal axis, whereby at least two portions of the T cross-section comprise helically extending mixing and/or conveying elements. Also disclosed is a method for manufacturing such a device.
