Toner is moved from the toner bottle to the sub hopper, and then to the development unit. It is transported by two augers that mix the toner with the developer until the mixture reaches the development sleeve roller.
- The developer (toner/carrier mixture) is smoothed to an even thickness on the development sleeve by the doctor blade before the toner is passed onto the surface of the drum.
- There are two development sleeve rollers, if the supply of toner to the development sleeve above is insufficient then the development sleeve below can make up for the deficiency.
- Any carrier from the developer that adheres to the drum is collected by the toner collection roller.
- The developer transported by the development sleeve roller and toner collection roller falls onto the transport auger below and is circulated.
