摘要： A toner cartridge has a toner storage chamber, a discharge outlet, a conveying screw, and a blocking wall. The discharge outlet serves to send out toner stored in the toner storage chamber, and the conveying screw serves to convey the toner stored in the toner storage chamber. Further, before the toner cartridge mounted into an image forming apparatus, the blocking wall is located in a space between a toner area, which is an area in the toner storage chamber where the toner exists, and the discharge outlet, thereby putting the space in a blocked state. The toner cartridge further includes a driving mechanism for, when the toner cartridge has been mounted into the image forming apparatus, driving the conveying screw by power transmitted from the image forming apparatus, so as to cancel the blocked state.

摘要： A toner carrying device includes a flexible sheet, and a sheet moving mechanism for allowing the flexible sheet to move back and forth by pulling the flexible sheet. In the flexible sheet, a toner passage hole for leaving a first opening section of a toner carrying pipe to open is provided. In a case where the toner passage hole is divided into first through three areas in such a manner that (i) the first area is provided on a side of one end of the flexible sheet in a direction orthogonal to a moving direction of the flexible sheet; (ii) the second area is provided on a side of the other end of the flexible sheet in the direction orthogonal to the moving direction; and (iii) the third area is provided between the first area and the second area, the third area extends broader in the moving direction than respective of the first and second areas. This allows the flexible sheet partially having the toner passage hole in its area to move smoothly.

摘要： By rotating a first and a second screw axle, developer is repeatedly cyclically carried from a first developer path, via an opening portion, a second developer path and an opening to return to the first developer path. While being recirculated and carried, the developer is stuck to an external peripheral face of a development roller, and is carried to a development region between the development roller and a photosensitive drum, wherein an electrostatic latent image on the photosensitive drum is developed by the toner. Furthermore, a first cut-out portion is formed on the first screw axle, and a second and third cut-out portions are formed on the third screw axle, and thus by allowing the developer to back flow from the recycle transport path to the toner supply path, the developer can mix with the toner in the toner supply path, and it is possible to prevent solidification of the toner in the toner supply path.
摘要翻译：通过旋转第一和第二螺旋轴，显影剂经由开口部分，第二显影剂路径和开口从第一显影剂路径反复循环地运送以返回到第一显影剂路径。在再循环和携带的同时，显影剂被粘附到显影辊的外周面上，并被承载到显影辊和感光鼓之间的显影区域，其中感光鼓上的静电潜像由调色剂显影。此外，第一切割部分形成在第一螺旋轴上，第二和第三切口部分形成在第三螺旋轴上，因此通过允许显影剂从循环输送路径返回到调色剂供应路径，显影剂可以与调色剂供应路径中的调色剂混合，并且可以防止调色剂供应路径中的调色剂的固化。

摘要： A waste developer collecting device ejects and collects a waste developer used in a developing unit employing a two-component developing system in which a developer that contains toner and carrier is used. The waste developer collecting device includes: an opening and closing section for opening and closing a developer ejection opening formed on a bottom portion of the developing unit; an opening operation prohibiting section for prohibiting the opening operation of the opening and closing section; a collecting container for collecting the developer ejected through the developer ejection opening; and a collecting container fixing section for fixing the collecting container at a position where the developer ejected from the developing unit is collected. The opening operation prohibiting section allows the opening operation of the opening and closing section when the collecting container is coupled to the collecting container fixing section.

摘要： A developing unit includes a developing hopper for storing a dual-component developer. In the developing hopper, an opening portion is formed at the position opposing the outer peripheral surface of a photoreceptor drum. A developing roller for supplying the developer to the photoreceptor drum to develop an electrostatic latent image is provided inside the developing hopper. The developing roller has a multi-pole magnetic member having a multiple magnetic poles and a non-magnetic sleeve. The multi-pole magnetic member has a multiple number of magnetic poles radially arranged apart from each other. The photoreceptor drum incorporates an opposing magnetic pole formed of a bar magnet having a rectangular section, disposed at a position opposing the magnetic pole across a photosensitive layer. The opposing magnetic pole has a polarity dissimilar to that of the main magnetic pole.
