PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2018 - IPC G03G15/08 

FIELD: image forming devices.

SUBSTANCE: present invention relates to a process cartridge mounted with the possibility of replacement in an image forming device and an image forming device, including a process cartridge. Declared group of inventions includes an image forming device including a main module and a process cartridge. At that, the process cartridge comprises a photosensitive drum, a rotated developing roller for developing an electrostatic latent image, formed on said photosensitive drum, a roller feeding the developer provided in contact with the said developing roller to feed the developer to the said developing roller, receiving the driving force section to receive the driving force, wherein the said receiving the driving force section is provided on the end section of the axis of the said feeding the developer roller and is movable relative to said developer feeding roller in a direction, intersecting the axis of said developer feeding roller, a first transferring the driving force section to transfer the driving force received by the said receiving the driving force section, onto the said developing roller, wherein the said first transmitting the driving force section is provided on the said feeding the developer roller, and a second driving force transmitting portion, provided on said development roller, for transferring driving force from said first driving force transmitting section to said development roller, wherein the said developing roller rotation direction is an opposite direction relative to the direction of rotation of the said feeding the developer roller, and surface speed of the said feeding the developer roller is more than surface speed of the said developing roller.

EFFECT: technical result is providing the process cartridge and the image forming device, in which, in a design, in which a developer is drawn from a developer containing chamber, provided below the developing chamber, to the developing chamber above the developer storing chamber providing reducing residual developer thus reducing the number of parts.
