    • An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developer supplying unit that supplies developer by being driven at a predetermined speed; a developing unit that develops the electrostatic latent image, while a transporting member transports the developer, a transport speed of the transporting member being switched to a plurality of speeds; a determining unit that determines whether or not an operation where a supply capacity of the developer supplying unit is greater than a transport capacity of the developing unit exceeds a predetermined threshold value and is continued; and a controller that performs control so that, when the determining unit determines that the operation exceeds the predetermined threshold value and is continued, an operation that was being executed immediately prior to the determination is stopped to forcefully drive the transporting member of the developing unit for a predetermined driving time.

    • A developer container is provided with a container body. An opening is formed through the container body. An opening/closing lid closes the opening. A lid holding frame holds the opening/closing lid in such a manner that the opening/closing lid can move between an open position and a closed position. A stopper stops the opening/closing lid and thereby preventing it from moving toward the open position in a state that the opening/closing lid is located at the closed position. A contact portion comes into contact with a hook portion provided in a container receiving portion when the developer container is inserted into the container receiving portion. A deformable portion deforms the stopper to such an extent that the stopping of the opening/closing lid by the stopper is canceled when the developer container is inserted into the container receiving portion and the contact portion comes into contact with the hook portion.
    • 显影剂容器设置有容器主体。 通过容器主体形成开口。 开/关盖关闭开口。 盖保持框架以使开/关盖能够在打开位置和关闭位置之间移动的方式保持打开/关闭盖。 止动器在打开/关闭盖位于关闭位置的状态下停止打开/关闭盖,从而防止其向打开位置移动。 当显影剂容器插入容器接收部分时,接触部分与设置在容器接收部分中的钩部接触。 可变形部分使止动件变形到当显影剂容器插入到容器容纳部分中并且接触部分与钩部接触时,通过止动件停止打开/关闭盖的程度。
