The copier is provided with a toner recycling mechanism. The toner, which has been
scraped off the surface of the PC Drum by the Cleaning Blade and collected in the Cleaning
Unit, is conveyed by the two Toner Recycling Coils to the Toner Supply Port and, from
there, it is returned back to the Developer Mixing Chamber of the Developing Unit.
One of the gears of the Toner Recycling mechanism receives drive through a gear at the
rear end of the PC Drum.
