摘要： A developer cartridge is described. The developer cartridge detachably mountable on a tandem type photosensitive unit slidable to a drawn-out position and a mounted position with respect to an image forming apparatus body may include a casing; a developer carrier rotatably supported on one end portion of the casing for carrying a developer; a pair of upright portions arranged on another end portion of the casing at an interval from each other in the axial direction of the developer carrier to extend from another end portion of the casing in a detaching direction for the developer cartridge; and an elastically deformable coupling portion extending in the axial direction of the developer carrier for coupling the upright portions with each other.

摘要： A developing frame has: side walls that support ends of a developing roller shaft; a connecting wall that connects the side walls, the connecting wall being pressed by first and second pressing members; and a handle extending from the connecting wall in a second direction perpendicular to a first direction. The handle is located farther away from the developing roller than the connecting wall is in the second direction. A drum frame has a supporting wall that supports the first and second pressing members. The supporting wall has an opening that is located between the first pressing member and the second pressing member. The opening allows the handle to be exposed when the developing cartridge is mounted on the drum cartridge. The supporting wall overlaps the handle as viewed from the first direction in a state where the handle is exposed through the opening.

摘要： An imaging unit for an electrophotographic image forming device having positional control features for aligning the imaging unit in a supporting frame in the image forming device. The positional control features include on each end wall, first and second bullet noses and a stop arm positioned between the two bullet noses. The first and second bullet noses engage support or datum surfaces provided in corresponding openings in the frame. The stop arm receives a biasing force that rotates the imaging unit into its final operating position. A latching assembly is provided on one end wall to prevent the imaging unit from ejecting from the frame.
