    • An image forming apparatus comprises a cartridge equipped with a toner reservoir, and an apparatus body. The cartridge is attached to the apparatus body when used and developer in the toner reservoir is used for image development. The cartridge comprises a storage unit which is provided inside the toner reservoir and capable of communicating with the apparatus body. The apparatus body comprises a communication unit which is capable of communicating with the storage unit and communication state between the storage unit and the communication unit varies depending on amount of residual developer in the toner reservoir. Thus there is provided a developer cartridge and an image forming apparatus surely capable of carrying out both residual-toner-amount detection and transmission of cartridge information with space saving design.
    • 图像形成装置包括装备有调色剂储存器的盒和装置主体。 当使用时,盒被附接到装置本体,并且调色剂储存器中的显影剂用于图像显影。 墨盒包括一个储存单元,该存储单元设置在调色剂储存器的内部并且能够与装置主体连通。 装置主体包括能够与存储单元通信的通信单元,并且存储单元和通信单元之间的通信状态根据调色剂储存器中的残留显影剂的量而变化。 因此,提供了一种显影剂盒和图像形成装置,其确实能够以节省空间的设计执行墨粉盒信息的残留墨粉量检测和透射。

    • An image forming apparatus includes a plurality of printing units each having an image bearing member for rotation about an axis and a process member which cooperates with the image bearing member in an image forming process; a transfer member for moving in contact with the image bearing member of each of the plurality of printing units, an image on each of the image bearing members being transferred onto the transfer member or a recording medium that is transported on the transfer member; a switch unit for switching between a contact state where the image bearing members in the plurality of printing units are in contact with the transfer member and a separate state where the image bearing member(s) in the printing unit(s) other than one of the plurality of printing units are separated from the transfer member; a memory for storing life expectancies of the image bearing member and the process member with regard to the printing unit(s) other than the one of the plurality of printing units; and a control section for controlling the switch unit based on a print job and the life expectancies stored in the memory.
    • 图像形成装置包括多个印刷单元,每个印刷单元具有用于围绕轴线旋转的图像承载部件和在图像形成工艺中与图像承载部件协作的处理部件; 用于与多个印刷单元中的每一个的图像承载部件接触移动的转印部件,每个图像承载部件上的图像被转印到转印部件上或在转印部件上传送的记录介质上; 开关单元,用于在多个印刷单元中的图像承载部件与转印部件接触的接触状态与在印刷单元中的图像承载部件之外的单独状态之间切换, 多个打印单元与传送构件分离; 用于存储图像承载部件和处理部件相对于多个印刷单元之外的打印单元的预期寿命的存储器; 以及控制部分,用于基于打印作业和存储在存储器中的预期寿命来控制开关单元。
