The composition of toner is composed of four components: polymer resin, charging agent, black agent, and additives.

The polymer resin accounts for 80% of the total toner powder, the charging agent accounts for 5% of the total toner powder,

the black agent accounts for 7% of the total toner powder, and the additives account for 8% of the total toner composition.

  Toner particles have very strict diameter requirements. After several times of practice and scientific and technical analysis,

it has been shown that the closer the particle diameter is to the standard and the ideal level, the better the printing effect will be.

  If the particle diameter is too thick or the size is different, not only the printing effect is not good, but also it will cause a lot of waste and loss.

  The toner used in general black toner printers is basically in a static state with “-”, the powder in the toner bin is also “-”, and the photosensitive drum has a “+”.

  The printing principle in printers; same sex repels, opposite sex attracts. Therefore, when the toner comes out of the toner bin,

passes through the toner supply roller and runs in the same direction as the photosensitive drum, and the positively charged photosensitive

drum absorbs the powder particles of the toner supply roller in its vacant part to complete the printing process.

  The original toner of the laser printer can be added toner after it is used up. Generally, about 2-3 words of toner can be added.
