Abstract:
A development apparatus 8 has developer transport members 26 and 27 respectively contained in containers 22 and 23 and transporting developer while stirring the developer and passing the developer to each other at a passing portion 41 and a passing portion 42, thereby causing the developer to circulate in a developer tank 21. The passing portion 41 is formed at a location of a partition 21c adjacent to a developer discharging mechanism 34 and the passing portion 42 is formed at a location of the partition 21c away from the developer discharging mechanism 34. The passing portions 41 and 42 have configurations in which a transport force acting on the developer at the passing portion 41 is greater than the transport force acting on the developer at the passing portion 42.
