A developing cartridge
By designing a conical powder delivery roller and a co-rotating gear system in the developing chamber, the contact area between the powder delivery roller and the developer is increased, solving the problem of poor developer delivery and improving image quality.

AI Technical Summary
The developer delivery in the existing developer cassette is ineffective, resulting in insufficient image quality.
A novel developer cartridge structure is designed, wherein the outer surface of the powder feeding roller is tapered to increase the contact area with the developer inside the powder hopper, and the developing roller, powder feeding roller, stirring frame and other components are rotated in coordination through a coupling gear system to ensure close contact between the powder feeding roller and the developing roller.
This improved the powder feeding quality of the powder feeding roller, thereby enhancing the imaging quality of the developing cartridge.
