This results in the addition of a set amount of toner from hopper 35 to the developer mix in sump 27. Conveyer 29 feeds developer mix to hopper 32, which fills until surplus developer spills between guide plate 71 and the conveyer. Opening of closure plate 33 releases a controlled flow of developer mix on to drum surface 28. |
