Description

そこで、上記課題を解決するために、トナー及びキャリアを有する現像剤が収納される第一室と、前記第一室との連絡路を通じて現像剤が循環する循環経路を形成する第二室と、前記第一室に設けられ、現像剤を前記第二室へ向けて搬送する第一搬送部材と、前記第二室に設けられ、現像剤を前記第一室へ向けて搬送する第二搬送部材と、前記第二室の開口部に設けられ、磁力により表面に現像剤を担持するとともに、像担持体の表面に形成された潜像を現像する現像剤担持体と、前記第一室に現像剤が封止されるように前記連絡路を封止する封止部材と、を有し、前記封止部材が開封されることで現像剤担持体に現像剤が供給可能となる画像形成装置であって、前記封止部材の開封動作を開始した後で、前記封止部材の開封動作が完了する前に、前記第一搬送部材が駆動されるように前記第一搬送部材の駆動を制御するコントローラと、を有することを特徴とする。 Therefore, in order to solve the above problems, a first chamber in which a developer having toner and a carrier is stored, a second chamber that forms a circulation path through which the developer circulates through a communication path with the first chamber, A first conveying member that is provided in the first chamber and conveys the developer toward the second chamber, and a second conveying member that is provided in the second chamber and conveys the developer toward the first chamber. A developer carrying member that is provided in the opening of the second chamber and carries a developer on the surface by a magnetic force and develops a latent image formed on the surface of the image carrier, and development in the first chamber. An image forming apparatus capable of supplying the developer to the developer carrying member by opening the sealing member. Then, after the opening operation of the sealing member is started, the opening operation of the sealing member is completed. To the first conveying member and having a controller for controlling the driving of the first conveying member to be driven.

Claims

A first chamber containing a developer having toner and a carrier; a second chamber forming a circulation path through which the developer circulates through a communication path with the first chamber; and the developer provided in the first chamber. A first conveying member that conveys the developer toward the second chamber; a second conveying member that is provided in the second chamber and conveys the developer toward the first chamber; and an opening of the second chamber. A developer carrier for developing a latent image formed on the surface of the image carrier, and a developer carrier on the surface by magnetic force, and the communication so that the developer is sealed in the first chamber An image forming apparatus capable of supplying a developer to the developer carrying member by opening the sealing member, wherein the sealing member is opened. The first conveying member is driven before the opening operation of the sealing member is completed. Developing apparatus is characterized by comprising a controller for controlling the driving of the sea urchin said first conveying member.

The communication path includes a first communication path for transferring developer from the first chamber to the second chamber, and a second communication path for transferring developer from the second chamber to the first chamber. the developing device according to claim 1, characterized in that said sealing member is provided so as towards the first communicating passage is opened earlier than the second communication path.

The opening operation of the sealing member is completed after the first conveying member is driven in a state where the opening operation of the sealing member is stopped in the middle of the opening operation of the sealing member. The developing device according to claim 1 or 2 .

The drive mechanism includes a rotation shaft to which one end of the sealing member is attached, and a drive source that rotates the rotation shaft, and the diameter of the rotation shaft is a seal that seals the first communication path. development according towards the portion stopper portion is attached, any one of claims 1 to 3, wherein greater than the portion sealing portion for sealing the second communication path is attached apparatus.
