DEVELOPING DEVICE, PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2019 - IPC G03G15/08 

FIELD: physics.

SUBSTANCE: present invention relates to a developing device which exhibits a latent electrostatic image formed on a photosensitive drum and is configured to be attached to the main body of the image forming / separation device, as well as to the process cartridge, which forms a developer image on the photosensitive drum and is configured to be attached to the main body of the image forming / separation device. Disclosed group of inventions includes versions of cartridges and imaging devices. At that, cartridge comprises: housing, developing roller, with possibility of rotation supported by housing, guide element provided side of cartridge, wherein the guide member is rotatable between a first position relative to the body and a second position relative to the body, a limiting lever configured to move between the limiting position and the non-limiting position, wherein the limiting lever is connected during operation to the guide member such that (i) when the limiting lever is in the confining position, the movement of the guide member relative to the body is limited, and (ii) when the limiting lever is in the non-limiting position, the movement of the guide member relative to the body is not limited, and a spring configured to squeeze the limit arm in the direction of the limiting position from the non-limiting position.

EFFECT: technical result is preventing the upsizing of the developing cartridge serving as a developing apparatus.
