摘要： A developing device comprising: a developing magnet roller for feeding developer onto a photoreceptor; a shutter mechanism for switching from feeding developer to the developing magnet roller to suspending the above supply, or vice versa; a delivery magnet roller for receiving developer from the developing magnet roller and conveying it to a path leading to the shutter mechanism; a toner feed path for interconnecting a toner hopper disposed at the upper end of a main body of the developing device and the space above the shutter mechanism. In order to prevent toner from escaping through a gap formed between the toner hopper and its lid, the developing device is designed to have an interconnecting path for interconnecting the space in the vicinity of the toner feed path within the main body and a different space within the main body, or to have, within the toner hopper, a guide member for guiding air that has come into the toner hopper from the main body through the toner feed path, so as to avoid a gap between the toner hopper and its lid, thereby preventing toner from scattering outside the developing device through the above gap.

摘要： A developing unit comprises a magnet roller, a stirring roller, a carrying screw, a toner density sensor, and a sensor level adjusting device. When feeding or exhausting the developing powder, the rollers and screw are driven at a slower or faster rotary speed than the speed given when developing an image. After the supply of the developing powder is terminated, the rotary speed of the rollers and the screw is changed to the speed given for developing an image. After a certain time is elapsed, the adjusting device serves to start the level adjustment when the sensor produces a stable output.

摘要： Disclosed is a method of determining the density of toner in the developer in an image forming apparatus by the use of a density sensor which is located beside a stirring member for stirring the developer. The density of toner is repeatedly measured at regular intervals for a predetermined period of time, which is the time required for the stirring member to make one complete revolution or a plurality of complete revolutions. The measured values of toner density are averaged, so that the mean value is taken as the density of toner in the developer. Since the values of toner density are averaged over the above-mentioned predetermined period of time, the unevenness in the toner density caused by the revolution of the stirring member is leveled off, thereby attaining accuracy in the determination of the toner density. Also because the density sensor is located beside the stirring member, the height of the developer tank can be kept small.
摘要翻译：公开了通过使用位于搅拌构件旁边的用于搅拌显影剂的密度传感器来确定图像形成装置中的显影剂中调色剂的密度的方法。调色剂的密度以规定间隔重复测量预定时间，这是搅拌构件进行一整圈或多次完整旋转所需的时间。将调色剂密度的测量值平均，使得平均值取为显影剂中调色剂的密度。由于调色剂浓度的值在上述预定时间内是平均的，所以由搅拌件旋转引起的调色剂密度的不均匀性被调低，从而获得了确定调色剂密度的精度。此外，由于密度传感器位于搅拌构件旁边，所以显影槽的高度可以保持较小。

摘要： A developing device for an electrophotographic copier includes a shutter along its toner supply route and a toner concentration detector sensor connected to a timing circuit. If the toner concentration is detected low, the timing circuit causes the toner supply to continue even after development is completed and the shutter is closed. An auxiliary stirrer is provided to keep stirring freshly supplied toner even after development is completed and the shutter is closed.

摘要： A toner hopper is arranged to feed the toner stored in itself to a developing unit and have a stirring roller and a feeding roller respectively supported rotatably, an interlocking mechanism for transmitting the force of rotation to the stirring roller, a manually rotating mechanism for manually rotating the stirring roller, and an interlocking restricting mechanism. The interlocking mechanism restricts the operation of the interlocking mechanism such that the force of rotation of the stirring roller is not transmitted to the feeding roller while the manually rotating mechanism supplies force of rotation to the stirring roller.

摘要： In an image forming apparatus having a developing unit for developing an image using toner, a toner box for withholding the toner, and a toner transportation section for transporting the toner withheld in the toner box to the developing unit, the toner transportation section includes a transportation screw portion having formed a spiral blade section on its shaft, a pipe section for controlling a toner transportation route by covering the transportation screw portion of the toner transportation section, and a toner flow suppressing section for suppressing flow of the toner from a space between the transportation screw and pipe section. Consequently, a toner transportation opening formed near the transportation section can be closed, and therefore, the flowing of toner into the developing unit can be controlled or reduced by a simple and inexpensive arrangement.
