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： 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： For realizing a satisfactory and stable developing process, the charge state of a developer and the density of toner particles contained in the developer is kept constant in the developing process. A developing roller to be driven rotationally is provided in a developing tank containing a developer. The developer is sucked magnetically using the magnetic force of a magnet provided in a developing sleeve composing the developing roller. The developer is then fed into a developing area opposed to a photosensitive member, then collected into the developing tank after the developing process is ended. The magnet is composed of an odd number of magnetic poles; developing pole, feeding pole, magnetic force distribution adjusting pole, developer sucking pole, developer separating pole, auxiliary collecting pole, and collecting pole. Between the sucking pole and the developing pole, an even number of poles are disposed. Between the developing pole and the separating pole are disposed an even number of poles. Consequently, the developer used for visualizing an image is separated while it is stuck on the developing sleeve when the developer is separated at the separating pole. When the developer is replaced, sticking of toner on the developing sleeve can be reduced significantly. In addition, the supplied developer is fixed in both toner density and charging level at the developing pole in developing.
