PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2017 - IPC G03G15/08 

FIELD: printing.

SUBSTANCE: present invention relates to a process cartridge mounted with the possibility of replacement in an image forming device and to the image forming device, which includes the process cartridge. Declared group of inventions includes an image forming device including a main module and a process cartridge. Herewith the process cartridge comprises: (i) a photosensitive drum, (ii) a rotated developing roller for developing an electrostatic latent image formed on the said photosensitive drum, (iii) a roller feeding the developer provided in contact with the said developing roller to feed the developer to the said developing roller, (iv) a receiving the driving force section to receive the driving force, herewith 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 in the direction crossing the axis of the said feeding the developer roller, (v) 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, herewith the said first transmitting the driving force section is provided on the said feeding the developer roller, and (vi) a second transferring the driving force section arranged onto the said developing roller to transfer the driving force by means of engagement with the said transferring the driving force section, herewith 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 with a design, in which the developer is delivered from a developer storing 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.
