ABSTRACT:
A developing unit includes a housing enclosing a mesh belt stretched across first and second rollers. The belt passes between a pair of friction plates that can be used to tribocharge toner particles carries on the mesh belt. Charging occurs over the large width of the entire mesh belt and the friction plates. Toner is transported on the surface of the mesh belt to a developing roller which, in turn, transports the toner to the surface of a photoconductor. The configuration of this developing unit reduces the loading associated with the tribocharging operation and the belt transport system reduces the volume of the developing unit.
