Toner production by suspension polymerization method

Toner is a familiar substance for people in the photocopying and printing industry. The toner that is mainly used is a uniform and soft powder that is used in different colors. Toner has different types and is produced by physical and chemical methods. In this study, using the suspension polymerization method, the ink or toner required in the electrophotographic printing process was produced using styrene, butyl acrylate monomers, and carbon black pigment. The produced toner was examined by determining the yield through gravimetry, thermal test, colorimetric test, and scanning electron microscope. The first experiment in this study was designed based on the optimal formulation from the studies, then the subsequent experiments were designed by changing the amount of three variables: stabilizer, pigment, and crosslinking agent as a single variable. Our goal is to optimize the formulation to increase the reaction efficiency and achieve the desired properties required for the printing toner.
