Abstract:
A development device can include a developer containing part containing developer, a carrier to carry developer that is supplied from the developer containing part to a development range, a partition dividing the developer containing part into a supply part and a circulation part beneath the supply part to collect developer from the carrier, a first transport member in the supply part of the developer containing part to supply developer from the supply part to the carrier, and a second transport member in the circulation part to transport developer in the circulation part in an axial direction of the carrier. The device can also include a removable seal member, which seals a supplied-developer and/or a collected-developer communicating area.
