Cartridge and image forming apparatus provided therewith

摘要

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.

1. A cartridge comprising:
a frame defining an internal space for accommodating therein developing agent, the frame being formed with a filling port for filling the internal space with the developing agent therethrough; a rotation body having a rotation axis extending in a predetermined direction, the rotation body being provided at the frame and rotatable about the rotation axis relative to the frame; a driving force transmission unit provided at the frame and configured to transmit an external driving force to the rotation body; a closing member configured to close the filling port; and a moving member configured to be irreversibly moved to one of a covered position and an exposed position by the external driving force transmitted through the driving force transmission unit, the moving member covering at least a portion of the closing member when the moving member is at the covered position, the moving member exposing the closing member when the moving member is at the exposed position, the exposed position providing an exposing degree greater than that at the covered position.
