Abstract
Disclosed is a developing cartridge in which a developer bearing member moves when a pressed part is pressed by a press member provided in a main body of an apparatus to move a developing frame in a state in which the developing cartridge is attached to the main body of the apparatus. The pressed part is provided with a positioning part that contacts and positions the press member. The press member is urged toward the positioning part by an urging member. The developing frame has a guiding part that moves the press member against an urging force of the urging member when the developing cartridge is attached to the main body of the apparatus.
Claims11
A developing cartridge attachable/detachable to/from a main body of an image forming apparatus, the developing cartridge comprising:
- a developer bearing member that bears developer to form a developer image on an image bearing member provided in the main body of the apparatus;
- a developing frame that supports the developer bearing member;
- and
- a pressed part that is provided on the developing frame,
- wherein, in a state in which the developing cartridge is attached to the main body of the apparatus, the developing frame moves when the pressed part is pressed by a press member, provided in the main body of the apparatus, to move the developer bearing member,
- wherein the pressed part is provided with a positioning part that contacts and positions the press member, and the press member is urged toward the positioning part by an urging member, and
- wherein the developing frame has a guiding part that moves the press member against an urging force of the urging member when the developing cartridge is attached to the main body of the apparatus.
