A toner cartridge is a cylinder coated with an organic material (selenium, a rare element), which is pre-charged, and when exposed to light, a resistive reaction occurs in the irradiated portion. The transmitted data signal controls the emission of the laser, and the light scanning on the surface of the toner cartridge changes continuously, so that some places are irradiated, the resistance becomes small, the electric charge disappears, and some places are not exposed to light, and the electric charge remains. The surface of the toner cartridge forms a latent image composed of electric charges.

How does the latent image become a truly copied image? Toner plays a key role. The toner is essentially a charged fine plastic particle whose charge is opposite to the polarity of the charge on the surface of the drum. When the surface of the charged drum passes through the applicator roller, it has a charge. The toner particles are adsorbed on the part, and the latent image becomes a real image. While the toner cartridge is rotating, another set of drive system feeds the copy paper, and the copy paper is charged with the same polarity but much stronger than the surface of the drum. Then the paper passes through the toner cartridge, and the toner on the surface of the drum is attracted. On top of the copy paper, the image is formed on the surface of the paper. At this time, the toner and the copying machine are merely combined by the attraction of the electric charge, and before the copying paper is sent out to the copying machine, the plastic toner is melted by the high temperature, and is solidified on the surface of the paper during the cooling process.

After the toner is attached to the copy paper, the surface of the drum continues to rotate, and after passing through a cleaner, the remaining toner is removed to enter the next copy cycle. It can be seen that the toner cartridge plays an important role in this process.

In fact, the toner cartridges of copier toner cartridge manufacturers are the key components of laser copiers. Because it not only determines the quality of the copy, but also determines the cost of copying. This is because in the laser copier, more than 70% of the imaging components are concentrated in the toner cartridge, and the quality of the copy is actually determined largely by the toner cartridge. The toner cartridge is also a consumable in the copier. After using it for a certain period of time and reaching a certain number of sheets, it needs to be replaced. Therefore, there is a lot of knowledge about choosing a toner cartridge suitable for a laser copier.
