Toner is the main consumable used in electrophotographic development processes such as electrostatic copiers and laser printers. It is composed of resin, pigment, additives and other ingredients. Its processing and preparation involve ultra-fine processing, chemicals, composite materials and other aspects, and is recognized as a high-tech product in the world. Since the advent of electrostatic copying technology, with the rapid development of information technology and office automation, the large number of laser printers and electrostatic copiers have required photocopies to have higher resolution and more suitable development density. The toner needs to have good particle shape, fine particle size, narrow particle size distribution, and suitable friction charging properties.
Qualified toner needs to meet the following requirements:
1. It is necessary to prevent impurities from polluting the toner, the electrostatic development process has high requirements for the toner, and the impurities mixed in the toner will directly damage the quality of the photocopy.
2. The collision and friction between the toner particles and between the particles and the wall will produce a strong electrostatic effect, and the electrostatic phenomenon will affect the safe operation when it is serious, and even cause more serious consequences, and the necessary anti-static measures should be considered.
3. Toner has adhesion, long-term accumulation will inevitably affect the smooth normal operation, and even lead to narrow or even blocked passage, necessary cleaning measures.
4. The toner is mainly organic matter, there is a possibility and hidden danger of dust explosion, which should not be taken lightly.
