5.1.3 Toner Cartridge (Development Section)
In the development stage toner particles are transferred from the toner cartridge onto the surface
of the OPC drum. The OPC drum and the developer roller rotate in opposite directions. Toner on
the developer roller is charged to the developing voltage (-370V ± 3%). Toner is attracted to the
OPC drum in those areas where the OPC drum surface charge is -50V. Toner is not attracted to
those areas of the surface carrying a -600V charge.
