Title:
PROCESSING CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2022/100705
Kind Code:
A1
Abstract:
A processing cartridge (1). The processing cartridge (1) comprises a cartridge body (A10), a photosensitive drum (20), a developing roller (30), a power receiving unit (21) and a pressing member (A40), wherein the photosensitive drum (20) and the developing roller (30) are rotatably arranged on the cartridge body (A10); the power receiving unit (21) is arranged on one end of the cartridge body (A10), and is used for being engaged with a driving unit (1080) of an electronic imaging apparatus (100), so as to receive a driving force output by the driving unit (1080); the pressing member (A40) is fixedly arranged on the cartridge body (A10), and is located at the same end of the cartridge body (A10) as the power receiving unit (21), and the pressing member is used for pressing the driving unit (1080), so as to correct the position of the driving unit (1080); and during the process of the power receiving unit (21) being engaged with the driving unit (1080), a displacement change does not occur in the pressing member (A40) with respect to the distance to the axis of the photosensitive drum (20). The process of bringing the photosensitive drum (20) or the developing roller (30) of the processing cartridge (1) into contact with the driving unit (1080) of the electronic imaging apparatus (100), and engaging the photosensitive drum or the developing roller with the driving unit is enabled to be smoother, thereby greatly shortening the time of the photosensitive drum (20) or the developing roller (30) being brought into contact with and engaged with the driving unit (1080), and improving the work efficiency of the processing cartridge (1).
