Description
Technical Field
The invention relates to the field of printing consumables, in particular to a developing assembly, a processing box and a working method of the processing box.
Background
A process cartridge is generally used in an image forming apparatus as a toner supply source for use in image forming, and an existing process cartridge is often detachably mountable to the image forming apparatus for use.
In general, a plurality of rotating work rolls, such as a toner feeding roll, a developing roll, a photosensitive drum, etc., which are commonly referred to as rolls, transmit power to each other through a gear system in a process cartridge. Currently, the process cartridge has two structures. The first type of the integral process cartridge as disclosed in U.S. patent document US5815644 has a photosensitive drum, a developing roller, a cleaning device, a charging device, etc., and the second type of the integral process cartridge as disclosed in U.S. patent document US6330410 has a drum cartridge including a photosensitive drum, a charging device, a cleaning device, etc., and a developing cartridge including a developing roller, a toner discharge blade, a toner feed roller, etc., and a developing cartridge detachably mounted on the drum cartridge.
Generally, a photosensitive drum is operated by receiving a driving force of an image forming apparatus through a driving assembly mounted at one end thereof, and a developing roller receives the driving force depending on the photosensitive drum through a gear system, as in a process cartridge disclosed in U.S. patent document US 6898399. In addition, the developing roller may also be operated by directly receiving a driving force from the image forming apparatus through a driving assembly mounted at an end thereof, so as to receive the driving force from the image forming apparatus independently of each of the photosensitive drums, as in the process cartridge disclosed in U.S. patent document US20080138115 A1. The driving force received by the developing roller is from outside the photosensitive drum and the image forming apparatus, and a driving assembly may be mounted on a side wall of the process cartridge frame, which receives the driving force of the image forming apparatus, and transmits the driving force to the developing roller through a gear system, as in the process cartridge disclosed in U.S. Pat. No. 7826767.
However, since the driving members are randomly swung under an unstressed state, the driving members and the driving shaft are easily stuck to each other when the process cartridge is mounted or dismounted, and even the driving members and the driving shaft are damaged, resulting in that the process cartridge or the image forming apparatus cannot work normally. Simultaneously, the driving component is structurally adaptive to the driving force receiving part, so that the driving component cannot use driving force receiving parts of other structures, and therefore the using requirements of different products and clients cannot be met, and further convenience cannot be provided for users.
