Abstract (en)
An electrostatographic apparatus comprising a developing device or a plurality of developing devices, intended for being used in a development system with a dry powder developer comprising at least toner- and carrier particles, that comprise(s) a container (11) for the developer wherein fresh toner can be mixed with said developer, as well as a container for fresh toner (16), characterised thereby that (i) the container for the developer does not comprise moving parts, (ii) said developing device comprises, or said plurality of developing devices comprise, means for changing the position of said container for the developer such as to mix the components of the developer, (iii) said container for developer has an output that directly connects to a magnetic brush (15) for applying toner to an electrostatic charge image on a dielectric material and an input through which fresh toner can be added. In a preferred embodiment in the container for developer a body has been provided whose outside wall runs substantially parallel with the inside wall of said container for developer so that an annular space is being defined for containing the developer and said inner body is said container for fresh toner. <IMAGE>
