Imaging cartridge with shiftable imaging components

An imaging cartridge installable in an image forming device, the image forming device including a rotational driving member and at least one cartridge guide defining a guide path, the cartridge comprising:

• a first cartridge portion engageable with the at least one cartridge guide for movement along the guide path;
• a second cartridge portion coupled to the first cartridge portion, the second cartridge portion including a drive receiving member configured for engagement with the rotational driving member and at least one of a drum unit assembly, a hopper, a developer roller, and a regulating blade, the second cartridge portion being moveable with respect to the first cartridge portion between a first position in which the drive receiving member is not engageable with the rotational driving member and a second position in which the drive receiving member is engageable with the rotational driving member;
• and
• a cartridge engaging mechanism to move the second cartridge portion relative to the first cartridge portion;
• wherein the cartridge engaging mechanism includes a force transfer surface for transferring and exerting a force from at least one of the first cartridge portion and the second cartridge portion to move the first cartridge portion;
• wherein the force transfer surface is a cam body moveably disposed on the first cartridge portion, wherein the cam body is engageable with the second cartridge portion to permit movement of the second cartridge portion between the first position and the second position;
• and
• wherein the cam body is a rotatable cam body having a first lobed portion and a second lobed portion, wherein the second lobed portion is larger than the first lobed portion.

• wherein the drive receiving member and the rotational driving member are decoupled when the second cartridge portion, and more specifically, the drum unit assembly is in the first position.

An imaging cartridge comprising:

• a first frame;
• and
• a second frame at least partially supported by the first frame and comprising a rotatable imaging component selected from the group consisting of a developer roller, a photoconductive drum, and a charging roller, wherein the rotatable imaging component is rotatable about an axis, and wherein the second frame is moveable relative to the first frame in a direction having at least a component that is parallel to the axis;
• and
• a cartridge engaging mechanism to move the second cartridge portion relative to the first cartridge portion;
• wherein the cartridge engaging mechanism includes a cam body moveably disposed on the first cartridge portion, wherein the cam body defines a force transfer surface that is engageable with the second cartridge portion to move the second cartridge portion between the first position and the second position;
• and
• wherein the cam body is a rotatable cam body having a first lobed portion and a second lobed portion, wherein the second lobed portion is larger than the first lobed portion.
