Abstract: If a user is not familiar with the operation for a developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. By increasing a rotation load of a second gear which is in an operable connection with a drive gear member of the developer receiving apparatus by a function of a locking member, the developer supply container mounted to the developer receiving apparatus is rotated toward the supply position. After the developer supply container rotates to the supply position, the locking by the locking member is released, by which the rotation load applied to the second gear is reduced, so that drive transmission, thereafter, to the feeding member for developer supply is smooth.

Abstract: In case of a developing density correction based on a test image (patch image) density, normally, the developing density is carried out in a short period of time by correction (γ correction) of a developing bias and a grid voltage (S11). When a correction amount of the γ correction exceeds an ordinary range, the γ correction (S11) and adjustment of toner concentration (magnetic permeability reference value) (S5) are carried out in combination. Furthermore, when the toner concentration is changed, the setting of a correction reference of the γ correction (γ correction TBL) and correction timing of the γ correction are accordingly changed (S6, S7). Therefore, in the developing density correction based on the test image density in the developing device using binary developer, it is possible to carry out the developing density correction, which is carried out in a short time, and whose correction width is wide, while maintaining the accuracy of a developing density adjustment.

Abstract translation: 在基于测试图像（贴片图像）密度的显影浓度校正的情况下，通常，通过显影偏压和电网电压的校正（伽马校正）在短时间内进行显影密度（S11） 。 当伽马校正的校正量超过普通范围时，组合进行伽马校正（S11）和调色剂浓度（磁导率基准值）（S 5）的调整。 此外，当调色剂浓度改变时，相应地改变伽马校正（伽马校正TBL）的校正基准的设置和伽马校正的校正定时（S6，S7）。 因此，在使用二次显影剂的显影装置中基于测试图像浓度的显影浓度校正中，可以执行在短时间内执行的显影浓度校正，并且其校正宽度大，同时保持 发展密度调整的准确性。

Abstract: An image forming apparatus includes an image forming mechanism configured to contain a developer and to form an image with the developer and a developer supplier configured to supply the developer to the image forming mechanism. The developer supplier includes a developer container, a conveyer, a sensor, an agitator, and a driver. The developer container contains the developer. The conveyer conveys the developer from the developer container to the image forming mechanism. The sensor is disposed at a predefined position on an interior wall of the developer container and detects the developer at the predefined position in the developer container. The agitator rotates to agitate the developer and includes a paddle formed in a plate-like shape and including an opening through which a part of the developer slips and avoids being paddled by the paddle. The driver drives the conveyer and the agitator at a variable speed.
