摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus preventing toner of an amount larger than necessary from flowing into a replenishing pipe or a developing device. SOLUTION: Part of a communicating part between the replenishing pipe and developing device is thinned. As a consequence, even when liquefied toner flows in at once to the developing device, the amount flowing into the developing device is restricted in the narrowed part. When feeding of the toner to the developing device is necessary, the communicating part is vibrated, and the toner is liquefied and passes through the connection part. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve a problem that a developer surface nearby a discharge hole for discharging an excessive developer does not become stable soon and the discharge of a developer possibly becomes unstable. SOLUTION: This developing device is so constituted that the sectional area of an agitation chamber is larger in an area nearby the discharge hole than in other areas. Thus, the developer surface nearby the discharge hole can be stabilized in a short period of time. Consequently, a system which discharges a developer from the discharge hole by using variation of a surface of a developer can stably be performed with high accuracy without making a developing container, specially, the agitation chamber large-sized.

摘要： PROBLEM TO BE SOLVED: To provide a developer container which is constituted of a small number of components and can be designed compact accordingly, and is equipped with a knob locking means hardly broken when dropping at transport.
SOLUTION: The developer container can be attached/detached to/from the image forming apparatus main body and supplies the developer to the image forming apparatus. The developer container is provided with the developer container main body for storing the developer; an opening part formed in the developer container main body in order to replenish the stored developer; a knob rotatably attached to the developer container main body and equipped with a drive transmission engagement part; and a container shutter for sealing the opening part so that the opening part can be freely open/closed and for opening/closing the opening part by receiving a rotary driving force from the knob. When the developer container is not loaded to the image forming apparatus main body, an engagement relation is established between the knob and the container shutter, then, the knob is locked so as not to be rotated, on the other hand, when the developer container is loaded to the image forming apparatus main body, the engagement relation is released when the container shutter slides in a direction different from a direction of opening/closing the opening part in accordance with the loading operation, then, the knob can be rotated.
