DEVELOPER CONTAINER, DEVELOPMENT DEVICE, AND IMAGE FORMATION APPARATUS
First Claim
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.

Abstract
A developer container includes: a developer container body including a developer supply port and a first shutter movement restriction groove on a surface of the developer container body; a shutter member movable from a close position to an open position of the developer supply port, the shutter member including a second shutter movement restriction groove such that the first and second shutter restriction grooves define a guide path when the shutter member closes the developer supply port at the close position; and a restriction member movable in the guide path and configured, when the restriction member is positioned in both the first and second shutter movement restriction grooves depending on an inclination of the developer container body, to prevent the shutter member from moving from the close position to the open position.
