Principles of Carrier Technology
Basic Function of the Carrier
- It mixes with toner and, through stirring and friction, imparts an appropriate charge to the toner.
- It uses electrostatic interaction to transfer the toner to the surface of the photosensitive drum for developing the image.
- It ensures the stable delivery of toner and supports the high-speed operation of the machine.
Development Trends of the Carrier
- Low density, high resistance, and smaller particle size.
- High-speed operation, longer lifespan, and higher image resolution.

Carrier Research Design
The Six Major Modules of Carrier
Design Research
Charge Design
The stability of the charge of the carrier and
toner is the most core and crucial issue.
1. If the charge is too low, it may lead to issues such as bottom ash, toner scattering, and the carrier failing to properly transport toner to the development roller.
2. If the charge is too high, it may cause problems such as poor print density.
3. The charge must remain stable under different temperature and humidity conditions.
