Technical Field

The present invention relates to a process cartridge detachably mountable in an image forming apparatus.

Background

An image forming apparatus is an image forming apparatus that forms a visible image on a recording medium by the principle of image formation, and includes an electrophotographic copying machine, an electrophotographic printer, an LED printer, and the like. Image forming apparatuses generally include a process cartridge detachably mounted therein, and the process cartridge often needs to be replaced as a consumable.

The existing processing box generally comprises two types, one type is an integral type, and the other type is a split type. The split type process cartridge is generally composed of two parts, i.e., a process cartridge and a photosensitive drum cartridge, which are combined by a specific connection manner. The process cartridge is generally composed of a powder hopper, an agitating frame, a powder feeding roller, a developing roller, a gear train, and the like, to supply the developer to the photosensitive drum cartridge. The photosensitive drum cartridge is generally composed of a waste toner hopper, a cleaning blade, a charging member, a photosensitive drum, and the like, wherein the photosensitive drum receives developer supplied from a developing roller to develop an electrostatic latent image. The imaging principle of the image forming device is as follows: the charging member charges the surface of the photosensitive drum uniformly, the light scanning unit in the electrophotographic apparatus irradiates light onto the surface of the charged photosensitive drum to form an electrostatic latent image, the developing roller transfers developer to the electrostatic latent image region of the surface of the photosensitive drum to form a visible developer image on the surface of the photosensitive drum, the transfer unit in the image forming apparatus transfers the visible developer image to a recording medium, and the visible developer image is fixed to the recording medium by fixing and discharged from the image forming apparatus.

Chinese patent publication No. CN102132219A discloses a process cartridge provided with a power receiving portion of a deflectable gimbal structure for engaging with a drive head in an image forming apparatus to receive a driving force from the image forming apparatus, which has a problem that, when the process cartridge is mounted in the image forming apparatus, the power receiving portion in the process cartridge may be stuck during deflection due to repeated deflection and not be normally engaged with the drive head in the image forming apparatus during engagement and disengagement with the drive head in the image forming apparatus, and at the same time, a pivot center of the gimbal structure may be released during transportation due to excessive vibration and cause the gimbal to fail.

In order to solve the above technical problems, chinese patent publication No. CN205844747U discloses a process cartridge, in which a power receiving portion is disposed to be not tilted and tilted, but the power receiving portion is disposed to be retractable along an axial direction of a photosensitive drum, and the structure can solve the technical problem that a pivot center of a gimbal structure may be loosened and cause a gimbal to fail due to excessive vibration during transportation, but because the power receiving portion in the structure adopts a manner of elastically retracting in the axial direction of the photosensitive drum, in a process of engaging the power receiving portion with a driving head in an image forming apparatus, a problem of unstable driving due to insufficient engagement of the power receiving portion and the driving head due to insufficient elastic force abutting against the power receiving portion is likely to occur.
