    • A developing cartridge for developing a latent image formed on the photosensitive member is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The developing cartridge includes a cartridge frame, a developer device for developing, with toner, the latent image formed on the photosensitive member of the main assembly of the apparatus when the cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, and a first projected portion projected from one longitudinal end of the frame. The first projected portion is supported by a first supporting member provided in the main assembly when the cartridge is mounted to the main assembly of the electrophotographic image forming apparatus. The cartridge also includes a second projected portion projected from the other longitudinal end of the frame. The second projected portion is supported by a second supporting member provided in the main assembly when the cartridge is mounted to the main assembly of the electrophotographic image forming apparatus. The cartridge further includes a driving force receptor member for receiving, from the main assembly of the device, a driving force for rotating the developer device when the cartridge is mounted to the main assembly. The driving force receptor member is exposed from the one longitudinal end. Also provided is a movable guide, provided in the cartridge frame for guiding the developing cartridge toward a mounting position when the cartridge is mounted to the main assembly.
    • 用于显影形成在感光构件上的潜像的显影盒可拆卸地安装到电子照相成像设备的主组件上。 显影盒包括盒架,显影装置,用于显影具有调色剂的墨盒,当墨盒安装到电子照相图像形成装置的主组件时形成在装置的主组件的感光构件上的潜像,以及 从框架的一个纵向端部突出的第一突出部分。 当盒被安装到电子照相成像设备的主组件上时,第一突出部分由设置在主组件中的第一支撑构件支撑。 盒还包括从框架的另一纵向端突出的第二突出部分。 当盒被安装到电子照相成像设备的主组件时,第二突出部分由设置在主组件中的第二支撑构件支撑。 该盒还包括一个驱动力接收件,用于从该盒的主组件接收用于当该盒被安装到该主组件上时使显影装置转动的驱动力。 驱动力接收构件从一个纵向端露出。 还提供了一种可移动导向件,设置在盒框架中,用于当盒安装到主组件时将显影盒引向安装位置。
