Abstract
A developing cartridge includes: a photosensitive unit; a developing unit coupled to the photosensitive unit to be movable between a release position and a developing position; an elastic member to provide an elastic force in a direction to maintain the developing unit at the developing position; a movable member including a gear portion, the movable member and capable of moving to a first position to move the developing unit to the release position and second position to move the developing unit to the developing position; and a switching member connected to a driving gear, wherein as the driving gear rotates in a first direction or a second direction, the switching member is switched between a third position at which the switching member is connected to the gear portion to move the movable member from the second position to the first position and a fourth position at which the switching member is spaced apart from the gear portion to allow the movable member to move from the first position to the second position.
