Abstract

Official abstract text for this publication.

A cartridge includes: a frame; a rotation body; a driving force transmission unit; a closing member; and a moving member. The frame is formed with a filling port for filling an internal space of the cartridge with a developing agent therethrough. The closing member is configured to close the filling port. The moving member is configured to be irreversibly moved to one of a covered position and an exposed position by an external driving force transmitted through the driving force transmission unit. The moving member covers at least a portion of the closing member when the moving member is at the covered position. The moving member exposes the closing member when the moving member is at the exposed position. The exposed position provides an exposing degree greater than that at the covered position.
