Abstract:
A developing cartridge includes: a frame defining a developer chamber for accommodating developer and being formed with an opening elongated in a longitudinal direction for allowing the developer to flow out of the developer chamber; a member assembled to the frame at a position opposite to the developer chamber with respect to the opening; a seal extending in the longitudinal direction and interposed between the member and the frame; and a protrusion protruding into the seal from at least one of the frame and the member in a protruding direction crossing the longitudinal direction, the protrusion being configured to restrict the seal from moving in the longitudinal direction.
