A universal developing cartridge detachably mountable in an electrophotographic image forming apparatus provided with two pairs of light emitters and light receivers, characterized by, include: A housing and a developing roller rotatably mounted on the housing, the housing containing a developer, the developing roller for conveying the developer outward, the developing roller rotating about a rotation axis in a first direction; The housing includes a bottom shell and a top cover, which together form a cavity for containing the developer; The universal developing cartridge also includes a driving end and a non-driving end located at the longitudinal end of the housing. The driving end is provided with a power receiving element for receiving driving force from the electrophotographic imaging setup. The housing has a first sidewall at the driving end and a second sidewall at the non-driving end. The cavity is located between the first sidewall and the second sidewall. The universal developing cartridge is also provided with a first detection part and a second detection part, and the housing is provided with a first mounting part and a second universal part. The first mounting part is used to accommodate the first detector, and the second universal part is used to accommodate the second detector. The first detector and the second detector are respectively used to cooperate with a pair of light emitters and light receivers to detect whether the universal developing cartridge is installed in the electrophotographic imaging device; The housing is also provided with a third general-purpose part, which is also used to accommodate the second detector; at least a portion of the second general-purpose part overlaps with at least a portion of the third general-purpose part.
2. The universal developing cartridge of claim 1, wherein, When the second detector is installed in the second general section and the third general section respectively, it corresponds to different models of developing cartridges.
3. The universal developing cartridge of claim 1, wherein, The first mounting part is provided with two mounting slots, namely a fourth mounting slot and a fifth mounting slot. Along the first direction, the fourth mounting slot is closer to the first sidewall than the fifth mounting slot. The first detector includes a first light input part and a first light output part. The first light input part is installed in one of the fourth mounting slot and the fifth mounting slot, and the first light output part is installed in the other of the fourth mounting slot and the fifth mounting slot.
4. The universal developing cartridge of claim 3, wherein, The second general-purpose part includes at least two mounting slots, and the third general-purpose part includes at least two mounting slots. The second general-purpose part and the third general-purpose part share at least one mounting slot.
5. The universal developing cartridge of claim 1, wherein, The bottom shell includes a variable body and a main body, wherein the variable body and the main body are combined to form at least a portion of the bottom shell.
6. The universal developing cartridge of any of claims 1-5, wherein, Both the second general section and the first mounting section are provided with five mounting slots.
7. The universal developing cartridge of claim 6, wherein, The developing chamber includes a power transmission assembly disposed on the same side as the power receiver, the power transmission assembly engaging with the power receiver, and both the power receiver and the power transmission assembly being fully exposed to the outside.
8. The universal developing cartridge of claim 6, wherein, The developing roller includes a developing roller shaft and a developing layer covering the outer surface of the developing roller shaft. The developer is carried by the developing layer. A recess is provided at the longitudinal end of the developing roller shaft. The developing cartridge is provided with an anti-detachment component to prevent the power receiving component from falling off the developing roller. The anti-detachment component is provided with a protrusion corresponding to the recess.
9. The universal developing cartridge of claim 6, wherein, The developing cartridge includes a powder feeding roller that contacts the developing roller and is used to deliver developer to the developing roller, and an agitator for stirring the developer and conveying the developer toward the powder feeding roller. Both the powder feeding roller and the agitator are rotatably disposed within the cavity. The power transmission assembly includes a first idler wheel, a second idler wheel, a powder feeding roller gear, and a stirring gear. The powder feeding roller gear is located at the longitudinal end of the powder feeding roller; the stirring gear is located at the longitudinal end of the stirring element; and the power receiving element is located at the longitudinal end of the developing roller, with both the power receiving element and the first idler wheel being helical gears. The first idler wheel meshes with the second idler wheel, the power receiving component, and the powder feeding roller gear, respectively; the second idler wheel meshes with the stirring component gear. Along the left-right direction, at least a portion of the first idler wheel is further away from the cavity than the second idler wheel, and the first idler wheel covers the second idler wheel; at least a portion of the second idler wheel is further away from the cavity than the stirring gear, and the second idler wheel covers the stirring gear.
10. The universal developing cartridge of claim 6, wherein, The non-drive end of the developing cartridge is provided with a conductive element for receiving power from the imaging device.
