The invention relates to a process for producing a surface-modified carbon-comprising support, which comprises the following steps: mixing of the carbon-comprising support with at least one metal compound, a carbon- andor nitrogen-comprising organic substance and optionally a dispersion medium, optionally evaporation of the dispersion medium at a temperature in the range from 40 to 200\xb0 C. The paper arranging apparatus of an electrographic image forming apparatus has a driving roller and an idle roller facing closely to each other and forming a nip therebetween. The wicket slot is adapted to receive and removably retain the wicket arms of a cartridge of wicketed bags. Further, the graphical user interface and method of the present invention allows an Agent access to non-managed applications without restricting the agent’s access to the managed applications.
