AI Technical Summary
Technical Problem
Conventional developing cartridges have a large size due to the positioning of components such as the coupling, detection gear, and IC chip on one side of the casing, leading to complex structures in both the cartridge and the image forming apparatus.
Method used
The coupling, detection gear, and IC chip are efficiently arranged on opposite sides of the developing cartridge casing, with the coupling and IC chip on one side and the detection gear on the other, allowing for a more compact design.
Benefits of technology
This arrangement reduces the overall size of the developing cartridge and image forming apparatus, simplifying their structures and improving efficiency.
