Recovered toner supply mechanism

The toner scraped off by the drum cleaning blade is transported by the toner recovery auger and the
toner recycling auger to be recycled, and then returned into the developer unit. Then the recovered
toner in the developer unit is mixed by the developer material using the mixer-3. The mixer-3 is
mounted exclusively for the recovered toner to mix it in a sufficient period of time. On the other hand,
the (fresh) toner transported from the toner cartridge into the developer unit is mixed by the mixer-2.
Then the (fresh) toner and the recovered toner are mixed together and further transported to the mixer-
1. They are further mixed by the mixer-1 and transported to the developer sleeve.
