Embodiment 1

[0041] Such as Figure 5 ~ Figure 7 As shown, a process cartridge 1 provided in the first embodiment includes a housing 2 which includes a frame body and side covers 4 located on both sides of the frame body. The frame body is provided with a developer containing chamber and a developing element 5; The end of the process cartridge 1 is provided with a drive assembly 6, a gear assembly 7, and the gear assembly 7 includes a gear 7a connected with the drive assembly, a developing element gear 7c and a powder feeding element gear 7b connected with the gear 7a, wherein the gear 7a is preferably The ground is a rotating element that receives the drive assembly 6; the drive assembly 6 includes: a drive head 61 that receives external power; a power transmission portion that transmits the power received by the drive head to the rotating element in the process cartridge, and the drive head 61 is relative to The power transmission part is movable. Preferably, the power transmission part is...

Embodiment 2

[0047] A process cartridge provided by the second embodiment also includes a housing, the housing also includes a frame body and side covers located on both sides of the frame body, a developer containing chamber, a developing element; a driving assembly, a gear assembly, and a gear assembly including and driving The gears connected to the components, the developing element gears and the powder feeding element gears connected to the gears, wherein the gears are preferably used as a rotating element that receives the drive assembly; and the driving force adjusting member is arranged such that the drive head 161 in the drive assembly is opposite to When the power transmission part moves, there is displacement in the axial direction of the rotating element and the direction perpendicular to the axial direction. The process box also includes a conical spring 167, one end of the conical spring 167 abuts against the inside of the cylinder 166, and the other end abuts against the step ...

Embodiment 3

[0051] Such as Figure 13 As shown, preferably, the third embodiment provides an image forming apparatus 1000 including: a frame (process cartridge accommodating portion) that accommodates a process cartridge, the frame includes an intermediate shaft, the entire frame can rotate around the axis of the intermediate shaft, and two Two discs are fixedly arranged on both sides of the intermediate shaft. The disc is equipped with gears. The gears cooperate with the gears on both sides of the rod 102. The gears on both sides of the rod 102 can drive the entire frame to rotate; and the rod 102 is made of metal. It can increase the rigidity of the frame; and the disk is provided with a partition that divides the frame into four small frames, so that the four processing boxes 1a, 1b, 1c, 1d can be installed in the frame at the same time. Four process cartridges (developer cartridges) of four colors, such as black (BK), blue (C), red (M), and yellow (Y), are installed at the same time; in...

Abstract

The invention provides a processing cartridge and an image forming apparatus comprising the processing cartridge. The processing cartridge comprises a shell; a developing agent accommodating chamber and a developing element are arranged in the shell; a driving assembly and a rotary element are arranged at the end part of the processing cartridge; the driving assembly comprises a driving head for receiving external power and a power transmission part for transmitting the received power to the rotary element in the cartridge; the driving assembly also comprises a guide rail formed in the shell, and a driving power adjusting member arranged between the driving head and the guide rail, wherein an inclined surface that is inclined relative to the axial line of the power transmission part is arranged on the guide rail; the driving head can move relative to the power transmission part; and the driving force adjusting member is connected with the driving head to enable the driving head to move in the axial direction of the rotary element when the driving head moves relative to the power transmission part. The technical problems that the complete coaxial effect cannot be reached, and the printing quality of products is influenced because of the existence of manufacturing tolerance due to the universal rotary driving head in the existing processing cartridge are solved.

Description

Technical field [0001] The present invention relates to the technical field of electrophotography, in particular to a process cartridge for an image forming apparatus and an image forming apparatus. Background technique [0002] Electrophotographic imaging equipment, as one of the image forming devices, such as laser printing, LED printers, and laser copiers, is very popular with users due to its advantages in printing costs. A laser printer in the prior art is usually provided with a detachable process box installed in the process box, and a rotating element is provided on the process box. These rotating elements include at least one of a developing element, a photosensitive element, and a charging element. These rotating elements serve as the process box. The necessary components of the laser printer can be directly or indirectly driven by the rotational force applied by the driving mechanism in the laser printer after being installed in the laser printer. [0003] Such as figur...
