In recent years, with the development of information technology and office automation, the use of a large number of laser printers and electrostatic copier, developer has higher resolution, more suitable for the consolidation temperature and the energy. Therefore, the lower the glass transition temperature of the toner has become a development trend. Production process has from the conventional melt crushing method to chemical polymerization method development, can be predicted, due to the advantages of chemical polymerization method, the trend to replace the melting method, but the chemical polymerization preparation process still need further perfect and mature. At present, the toner preparation technology is a research hotspot of chemical polymerization.
Printer toner compositions and functions of printer toner compositions and functions of print pieces of good or bad, mainly by the printer performance, the sensitivity of the photosensitive drum, the carrier of physical properties and the quality of printer toner this several aspects. Here we introduce the composition and role of the printer toner.
Printer toner of the main components of a resin: main imaging material, constitute the main body of the toner components: carbon black: the main imaging material, with the function of adjust the depth of color, commonly referred to as the blackness; magnetic iron oxide: to attract the magnetic force of the magnetic roller, carrying carbon adsorbed on the magnetic roller; particle charge control: control the electric quantity of the carbon powder, the carbon powder uniformly charged; lubricant (silicon particles): play the role of lubrication, and friction control charge; hot melt plastic (Plasticizer): toner melting point control, carrying carbon powder in molten state soak into the paper fibers, forming the final solid image.
