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.

1. A developing cartridge comprising:
a developing roller having a rotational axis extending in a first direction; and a casing, the developing roller being positioned closer to one side of the casing in a second direction perpendicular to the first direction than to an other side of the casing, the casing including a notched portion extending inwardly from an outer surface of the other side of the casing in the second direction, wherein the casing includes:
a first upright portion extending outwardly from the outer surface of the other side of the casing;a second upright portion extending outwardly from the outer surface of the other side of the casing, the second upright portion spaced apart from the first upright portion in the first direction;a coupling portion coupling the first and second upright portions and overlapping the notched portion in the second direction, wherein the coupling portion is deformable in the second direction; andan opposed portion disposed between the coupling portion and the notched portion in the second direction and between the first and second upright portions in the first direction, the opposed portion being spaced apart from the coupling portion in the second direction.
