Production of Laser Jet Printer Toner by in Situ Emulsion Polymerization Method

From the past to the present day, various methods of printing have been used in terms of application, among which the most widely used method of them is electrophotography. The increasing demand for this technique increases the importance of obtaining high-resolution images in electrophotography. Therefore, the processes and the materials that are used are continuously improving and progressing. In this paper, at the first the toner and its components are introduced, then the properties of toner that effect on its quality is expressed. Followed by, different methods of toner production, especially the in situ emulsion polymerization method are described. The emulsion polymerization can be of great interest in toner production because of its ability to form composite particles with encapsulated structure and spherical shape as well as high reaction conversion. In this regard, different effective parameters and components of this method to produce of toner are introduced. Finally, the benefits of this method are expressed in comparison to other production methods of toner.
