    • An image forming apparatus of the present invention includes an image carrier. A rotary developing device adjoins the image carrier and includes a plurality of developing sections for developing a latent image formed on the image carrier with a magnetic developer. A toner cartridge unit includes a plurality of toner cartridges and is rotatable integrally with the developing device. A plurality of toner conveying device each connect one toner cartridge to the associated developing section and each include a toner passage and a toner conveying member disposed in the toner passage. A magnet adjoins a toner outlet, which is formed in the toner passage and communicated to the developing section, for forming a magnetic field that traverses the toner passage over the entire diameter of the toner passage. Toner stored in each toner cartridge is prevented from unexpectedly flowing into the associated developing section when replenishment is not effected.
    • 本发明的图像形成装置包括图像载体。 旋转显影装置邻接图像载体,并且包括用磁性显影剂显影形成在图像载体上的潜像的多个显影部分。 调色剂盒单元包括多个调色剂盒,并且与显影装置一体地旋转。 多个调色剂输送装置将每个调色剂盒连接到相关联的显影部分,并且每个调色剂输送装置都包括调色剂通道和设置在调色剂通道中的调色剂传送部件。 磁体毗邻调色剂出口,该调色剂出口形成在调色剂通道中并与显影部分连通,以形成在调色剂通道的整个直径上穿过调色剂通道的磁场。 当不进行补货时,储存在每个墨粉盒中的墨粉被防止意外地流入相关的显影部分。
