AI Technical Summary

Technical Problem

The developer delivery in the existing developer cassette is ineffective, resulting in insufficient image quality.

Method used

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.

🎯Benefits of technology

This improved the powder feeding quality of the powder feeding roller, thereby enhancing the imaging quality of the developing cartridge.
