    • A toner supplying system for use in combination with a developing device (100) of the type having a conveyor means (300) carrying a plurality of developing units (101) such as to bring the desired developing unit to the developing position for the development of a latent image on an image carrying member (1). The toner supplying system comprises a hopper (201) disposed outside the developing device, a shaft (310) provided in the toner conveyor means, a toner transportation means (202) for transporting the toner from the hopper to the shaft, and a toner passage means (310, 350) through which the toner is supplied from the shaft to respective developing units. The toner passage means includes annular chambers (351) formed between the hollow shaft (310) and an intermediate pipe (350). The annular chambers are separated axially by partition sealing means (354). Toner passage means (225, 450), switchable between open and shut-off states and adapted to take the open state only when their associated developing unit is in a toner supplying position, are also provided. The system further comprises a toner density detecting means (50) for detecting the toner density in the developing agent on the developing unit under development. The toner density detecting means produces, when the detected toner density is too low, a signal for bringing the developing unit to the toner supplying position after completion of the development of the final color on a copying paper under developing operation.
    • 一种与显影装置(100)组合使用的调色剂供应系统,该显影装置具有承载多个显影单元(101)的传送装置(300),以将期望的显影单元带到展开位置 图像承载部件(1)上的潜像。 调色剂供给系统包括设置在显影装置外部的料斗(201),设置在调色剂输送装置中的轴(310),用于将调色剂从料斗输送到轴的调色剂输送装置(202) 装置(310,350),调色剂通过该装置从轴供应到各显影单元。 调色剂通道装置包括形成在空心轴(310)和中间管(350)之间的环形室(351)。 环形室由分隔密封装置(354)轴向分离。 调色剂通道装置(225,450)可在打开和关闭状态之间切换,并且仅在其相关的显影单元处于调色剂供应位置时才适于开启打开状态。 该系统还包括用于检测在显影单元下的显影剂中调色剂浓度的调色剂浓度检测装置(50)。 当检测到的调色剂浓度太低时,调色剂浓度检测装置产生在显影操作下在复印纸上完成最终颜色显影之后使显影单元进入调色剂供应位置的信号。

    • The present invention provides an apparatus wherein image fixing means is controlled for different fixing conditions under which a toner image is fixed on a recording material to adapt it to a synthetic resin sheet as the recording material or to a color image to be fixed, including at least one of fixing temperature, fixing speed and actuation of cleaning means. The present invention is particularly effective in use for a recording system in which the fixing temperature and speed are decreased and the cleaning means is actuated when a color image is to be formed on a transparent or resin sheet. The present invention is most useful for a color image recording system.

    • An image forming apparatus has at least one image carrier, a device for forming a latent image on the image carrier at a latent image forming position, a device for developing the latent image on the image carrier at a developing position, and a device for transferring the developed image on the image carrier onto an image receiving member. The apparatus features a drive source, and image carrier pulley connected to each of the at least one image carriers, a drive pulley connected to the drive source, and a device for transmitting a driving force from the drive pulley to each image carrier pulley. The time taken to rotate each of the at least one image carriers from the image forming position to the transfer position is substantially equal to an integer multiple of the time taken to make one revolution of the drive pulley.
