摘要： A developing device capable of preventing deterioration of the image quality, which is caused when a developer recovered by a developing roller re-adheres thereto, and an image forming apparatus equipped with the developing device. The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the amount of developer existing on the upstream side of the agitation conveyance path in the developer conveyance direction becomes small, whereby the developer can be delivered smoothly from the recovery conveyance path to the agitation conveyance path. Therefore, the bulk of the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from reaching the level where the recovered developer re-adheres to a developing roller, and further the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from re-adhering to the developing roller.
摘要翻译：一种能够防止由显影辊回收的显影剂重新附着的显影剂的图像质量劣化的显影装置和配备有显影装置的图像形成装置。在显影剂输送方向上的搅拌输送路径的上游侧的显影剂输送量比通过将回收输送路径向搅拌输送路径输送的显影剂的量变大，显影剂输送方向上的搅拌螺杆等于或大于在显影剂输送方向上的回收螺杆的下游侧的显影剂输送量。因此，显影剂输送方向上的搅拌输送路的上游侧的显影剂的量变小，能够使显影剂从回收输送路径平稳地输送到搅拌输送路径。因此，可以防止在显影剂输送方向上在回收输送路径的下游侧存在的显影剂的体积达到恢复的显影剂重新粘附到显影辊的水平，并且进一步存在于下游侧的显影剂可以防止显影剂传送方向上的恢复传送路径再次粘附到显影辊上。

摘要： A developing device capable of preventing scattered developer from being discharged and of stably supplying a developer to a latent image carrier by preventing the developer from being discharged despite that the amount of developer within the developing device is not increased, and an image forming apparatus including the developing device. When the bulk of the developer existing in the vicinity of the downstream end in the conveyance direction of the supply conveyance path exceeds the height level of the developer discharge port, the developer that has reached the height level of the developer discharge port is discharged to the outside of the developing device by the developer discharge port and developer conveyance path serving as the developer discharge means.

摘要： A developer container has a main part accommodating a developer therein and is detachably attached to a main part of an image forming apparatus. The developer container comprises an outlet provided at a side of the developer container to discharge the developer from the developer container. An input unit is provided adjacent to the outlet and has a small-diameter portion an inside diameter of which is smaller than a diameter of the container main part wherein, when the developer container is attached to the image forming apparatus, the input unit is engaged with a drive motor of the image forming apparatus to receive a rotating force of the drive motor. A developer guiding unit causes the developer inside the developer container to be moved to the outlet beyond the small-diameter portion of the input unit by rotation of the developer container.

摘要： An image forming apparatus of the present invention includes an apparatus body, an image carrier for carrying a latent image on its surface, and a developing device for developing the latent image to thereby produce a corresponding toner image. A removable member is removably mounted to the apparatus body and positioned in the apparatus body such that a distance between the removable member and a surrounding member around it varies when the removable member is being mounted to or dismounted from the apparatus body. A frame surrounds at least one of the removable member and surrounding member. A contact member contacts, when the removable member is being mounted to or dismounted from the apparatus body, the frame to thereby determine a distance between the removable member and the surrounding member.

摘要： An image forming apparatus includes an electrostatic latent image carrier carrying an electrostatic latent image and a development unit that develops the electrostatic latent image. The development unit includes a developer carrier, first, second, and third developer conveyers, and an opening area. The developer carrier is disposed opposing to the electrostatic latent image carrier. The first developer conveyer supplies a developer to the developer carrier. The second developer conveyer conveys the developer, and transports the developer to the first developer conveyer at a downstream side of the second developer conveyer. The third developer conveyer collects the developer, conveys the developer, and transports the developer to the second developer conveyer in a downstream side of the third developer conveyer. The opening area, disposed higher than a lowermost point of the first developer conveyer, allows the developer to drop from the first developer conveyer to the second developer conveyer.
