ABSTRACT:
The present invention provides a developing cartridge attachable to and detachable from a main body of an image forming apparatus comprising a cartridge frame, developing device for developing a latent image formed on an image bearing member, and a shutter member supported by the cartridge frame. The shutter member moves between a covering position for covering a portion exposed from the cartridge frame of the developing device and a retreat position retreated from the covering position. A sheet member, being flexible and interlocking with the shutter member, covers a part of the cartridge frame when the shutter member moves to the covering position. The cover member covers the gripping portion of the frame and a floating developer regulating member.
