Description

Technical Field

[0001] The invention relates to the technical field of toner, and in particular to an organic toner. Background Art

[0002] Graphite powder is a mineral powder whose main component is carbon. It is soft and black-gray in color. It feels greasy and can be used to print and dye paper. When oxygen is isolated, its melting point is above 3000°C, making it one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature and it is insoluble in water, dilute acids, dilute alkalis and organic solvents. Graphite materials have high-temperature resistant and conductive properties and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials, etc.
