Image forming apparatus and toner case

摘要

This image formation device is provided with a toner case (6), a developer body (83) and a developer (12). The toner case (6) includes a case body (22) having a discharge port (35), and a case-side shutter (28) for opening and closing the discharge port (35). A replenishing port (88) for accepting the toner is provided to the developer body (83). The developer (12) includes a developer-side shutter (98) for opening and closing the replenishing port (88). When the toner case (6) has been mounted on the developer (12) and the case-side shutter (28) is displaced from a position where the discharge port (35) is closed to a position where the discharge port (35) is open, the case-side shutter (28) pushes and displaces the developer-side shutter (98) from a position where the replenishing port (88) is closed to a position where the replenishing port (88) is open.
