Developer

Developer is the core consumable of the developing system for copiers and laser printers. As the key medium mixed with toner for image development, it adsorbs toner via magnetic force, charges toner through friction, and delivers toner evenly to the surface of the OPC drum. It is an essential material to guarantee perfect developing performance and controllable print density.

Materials & Characteristics: 

Made of high magnetic permeability and wear-resistant ferrite magnetic powder with special surface coating. It features uniform particle size and stable magnetism, outstanding triboelectric charging capacity, and forms a stable charging system together with toner. It delivers great fluidity, hardly agglomerates and resists abrasion effectively.

Core Function: 

The magnetism, particle size and charging property of developer directly affect the uniformity and stability of print density. It precisely controls toner feeding volume and charge level to reduce toner waste and background fog, and extends the service life of developer units. It is a vital consumable for consistent print quality and lower printing costs.
