Abstract:
1. A developer container comprising: a developer container body including a developer supply port configured to supply a developer stored inside the developer container body to outside the developer container body; and a first shutter movement restriction groove provided on a surface of the developer container body; a shutter member provided to be movable over a region of the developer container body from a close position to an open position of the developer supply port while being in a sliding contact with the surface where the first shutter movement restriction groove is formed, the shutter member including a second shutter movement restriction groove configured to form a guide path with the first shutter movement restriction groove by facing the first shutter movement restriction groove when the shutter member closes the developer supply port at the close position; and a shutter movement restriction member movably provided in the guide path formed by the first shutter movement restriction groove and the second shutter movement restriction groove, the shutter movement restriction member configured to be positioned in both the first shutter movement restriction groove and the second shutter movement restriction groove depending on an inclination of the developer container body, and thereby to restrict a movement of the shutter member in an open direction from the close position to the open position, wherein the first shutter movement restriction groove has a cross sectional shape in which a central side is recessed deeper than edges on both sides and is connected to the edges on both sides via inclined surfaces.
