The sub-hopper can hold Bk: 24.7 cc (equivalent to 230 sheets of 5% chart), or Color: 19.3 cc (equivalent to 150 sheets of 5% chart) of toner.

Toner which has fallen into the sub-hopper is homogenized by an agitator (Mylar sheet: 2 for BK, 1 for each color).

After being horizontally transported by the coil, toner in the sub-hopper falls directly into the development unit.
