Abstract

PURPOSE:To economically replace a developing tank by allowing a 2nd development part which has a toner agitator to be attached to and detached from a 1st development part. CONSTITUTION:The developing tank consists of the 1st development part 10 with a developing roller 2 and a toner concentration sensor 3 and the 2nd development part 11 with the toner agitator roller 4, and the 2nd development part 11 is detachable from the 2nd development part 11. When a developer 7 enters a lack state or when its life comes to the end, the 2nd development part 11 is detached from the 1st development part 10. Then a new 2nd development part 11 which is full of a developer 7 is attached to the 1st development part 10. In this case, the 2nd development part 11 has the inexpensive agitator roller 4, so it enables economic disposal replacement.
