1. A process cartridge, which is detachably mounted in an image forming device, wherein the image forming device has force applying components and a movable tray, the tray can move in a front-and-rear direction, a direction in which the tray is pushed into the image forming device is front, and a direction in which the tray is pulled out from the image forming device is rear; and the process cartridge can be mounted into the tray from top to bottom along a direction of gravity, the process cartridge comprising:
a photosensitive unit comprising a photosensitive drum and a support configured to support the photosensitive drum;
a developing unit, which is rotatable relative to the photosensitive unit, and comprises a developing roller and a developing frame configured to support the developing roller,
wherein the process cartridge has a driving side and a conductive side disposed oppositely along a left-and-right direction, and the driving side is provided with a first driving force receiving portion for driving the photosensitive drum to rotate and a second driving force receiving portion for driving the developing roller to rotate; and
a force receiving portion,
wherein the force receiving portion has a separating force receiving portion for receiving the force of one of the force applying components so that the developing unit rotates relative to the photosensitive unit to separate the developing roller from the photosensitive drum; and
wherein the developing frame comprises a sliding guide rail extending in the left-and-right direction, the force receiving portion is configured to slide in the sliding guide rail.
