摘要： A developing unit is intended to have a capability of efficiently exhausting developing powder. The developing unit is constructed to have a developing bath, one or more rollers for development, an exhausting mechanism for exhausting the developing powder out of the developing bath, a shielding member for shielding the exhausting mechanism from the developing bath or exposing it to the developing bath, and a control unit for controlling the rollers, the exhausting mechanism and the shielding member. When exhausting the developing powder, the control unit operates to drive the rollers and then activate the shielding member for exposing the exhausting mechanism to the inside of the developing bath after a certain time is elapsed since the rollers are driven. Further, a pair of rotary bodies may be provided in parallel for opening or closing the exhaust outlet of the developing bath selectively at a proper time.

摘要： A developing unit is configured to develop an electrostatic latent image born on an image bearing member with a developer that has been charged by mixing and agitating toner and magnetic carrier. The developing unit comprises a developing hopper; a developer bearing member; and at least a pair of agitating and conveying members rotationally driven in the developing hopper. The agitating and conveying members are arranged substantially parallel to the developer bearing member and each rotational shaft of the agitating and conveying members is embedded with a magnetic source element whose magnetic poles are laid out so as to produce a magnetic field radially oriented in a particular fixed direction with respect to the agitating and conveying member.

摘要： In a developing device including a developer tank having a developing area tank and an agitating tank, a first agitating member, a second agitating member, a toner hopper, and a toner storing container, a toner replenishing port is formed in an agitating tank, and two flows of the developer are produced by a rotation of the first agitating member provided with a first agitating blade and a second agitating blade, from both ends of a longitudinal direction of the developer tank to a vicinity of the toner replenishing port. These two flows collides with each other in a vicinity of the toner replenishing port to produce a pulsation flow of the developer from the toner replenishing port into the toner storing container through the toner hopper.

摘要： A developing device of an electrophotographic copier is structured separably into two mutually attachable and internally connected sections. One of these sections is disposed adjacent to the copier's photoreceptor and contains a developing roller and the other section distal from the photoreceptor is made of a relatively inexpensive synthetic resin material, including a stirrer roller. When the developing agent is spent, the two sections are separated and only the second part with the stirring roller is discarded for replacement. In order that the spent developing agent can be effectively collected, a bar magnet may be inserted into a chamber formed inside the shaft of the stirrer roller to make use of its magnetic force or a scrapper may be provided to scrape off the developing agent remaining attached to the developing roller. In the case of a clam shell type copier with a top part of the main body made openable rotatingly with respect to its base part, the developing device becomes tilted when the copier is opened for its replacement. A device for shaking the tank can effectively cause the developing agent remaining inside to move into the lower section of the device for easy collection.

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.
摘要翻译：一种显影装置，包括：用于将显影剂供给到感光体上的显影磁辊; 用于从供给显影剂切换到显影磁性辊以暂停上述供给的快门机构，反之亦然; 用于从显影磁辊接收显影剂并将其传送到通向快门机构的路径的输送磁辊; 用于将设置在显影装置的主体的上端处的调色剂料斗与快门机构上方的空间相互连接的调色剂供给路径。为了防止调色剂通过形成在调色剂料斗和其盖之间的间隙逸出，显影装置被设计成具有用于将主体内的调色剂供给路径附近的空间与主体内的不同空间相互连接的互连路径，主体，或者在调色剂料斗内具有用于引导通过调色剂供给路径从主体进入调色剂料斗的空气的引导构件，以避免调色剂料斗和其盖之间的间隙，从而防止调色剂通过上述间隙在显影装置外部散射。
