A toner cartridge, also known as a photosensitive drum, is generally composed of a base substrate made of aluminum and a photosensitive material coated on the substrate. The toner cartridge not only determines the quality of printing and copying, but also determines how much money the user has to spend in use.

    At the time of its birth, the inorganic material - selenium material was used to make the photosensitive drum. Selenium is allowed to adhere to the drum base by steaming to form a photosensitive drum. After the 1980s, the photosensitive drum has been made of organic light-guiding materials, which is cheaper and less polluted. However, since everyone is used to it, the drum is called a "toner cartridge." The purpose of the toner cartridge is very wide and needs to be used in printers, copiers and fax machines.

    In the copying machine, more than 70% of the image forming parts are concentrated in the toner cartridge, and the quality of the copying is actually largely determined by the toner cartridge. The toner cartridge of the copier toner cartridge manufacturer belongs to the consumables 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 to choose a toner cartridge suitable for the copier. Selenium is a non-metallic chemical element and the chemical symbol is Se. It can be used as a photosensitive material, a catalyst for electrolytic manganese industry, a nutrient element essential for animals, and a nutrient element beneficial to plants.

    The environmentally-friendly toner cartridge is used to disassemble and use the used old toner cartridge, clean, inspect, replace, and undergo a rigorous matching test to achieve the standard product. In economically developed regions such as Europe and the United States, the use of environmentally friendly toner cartridges has become very common. Seven out of every ten toner cartridges are environmentally friendly, and the use of environmentally friendly toner cartridges is an economical option.

    In terms of structure, the toner cartridges of copier toner cartridges are available in one piece (integral type) or in separate type. The integrated toner cartridge is equipped with a toner cartridge and a photosensitive drum on the same device. When the toner is used up or the photosensitive drum is damaged, the entire toner cartridge is scrapped. The separation toner cartridge and the photosensitive drum are placed on different devices, and the life of the photosensitive drum is generally long, generally reaching a life of 20,000 sheets. When the toner is used up, just replace it with new toner, so the user's printing cost is greatly reduced.
