Abstract:
A developing unit includes a developer cartridge having an outside frame and an inside frame that has a first opening. The first opening is movable between a first opening position where the first opening is opened and a first closing position where the first opening is closed by the outside frame. The developing unit further includes a first seal disposed around the first opening on the inside frame, a housing that includes a cartridge holding part for holding the developer cartridge and is capable of holding a developer holding member, and a capturing member which is provided on the cartridge holding part. The capturing member has a developer capturing force greater than that of the first seal, and is slide contactable with the first seal when the inside frame moves from the first opening position to the first closing position.
