PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2015 - IPC G03G16/00 

FIELD: physics.

SUBSTANCE: group of inventions includes process cartridges. Process cartridges comprise a light-sensitive element configured to transfer an electrostatic image, a developing roller configured to develop the electrostatic image, a housing which supports said light-sensitive element and said developing roller such that at least one of said light-sensitive element and said developing roller is movable between a contact position, in which said light-sensitive element and said developing roller are in contact, and a spaced-apart position in which said light-sensitive element and said developing roller lie at a distance from each other, and a movable element having a force-receiving end. Said movable element is configured to move between a first position and a second position. Said force-receiving end is closer to said housing when said movable element is in the first position than when said movable element is in the second position. Said movable element is connected to said housing such that when a force is applied to said force-receiving end of said movable element, when said movable element is in the second position, at least one of said developing roller and said light-sensitive element moves such that said light-sensitive element and said developing roller are in the spaced-apart position, as well as a first movable element and a second movable element, a connecting element, a movable element etc.

EFFECT: designing a smaller process cartridge in which the electrophotographic light-sensitive drum and the developing roller can be brought into contact with each other and separated from each other, and a smaller image forming device in which said process cartridge can be detachably mounted, and designing a process cartridge in which the electrophotographic light-sensitive drum and the developing roller can be brought into contact with each other and separated from each other, wherein the force-receiving portion is not damaged during manipulations with the process cartridge or when transporting the process cartridge.
