The printing process of photocopiers and laser jet printers are done by electrophotographic process based on the toner. Toner is the dry powder consisting of a polymer, dye, charge control agent and additives. Toner production methods are normally divided into two main chemical and pulverize methods. The emulsion aggregation is one of the chemical methods based upon the accumulation and changes in the pH of the emulsion .This process caused a gel to form toner particles. Thus, selection of raw materials is very important and can affect the production process of the toner. In this study, the effect of different types of carbon black with various particle sizes and structure is investigated. Survey results indicate that application of a carbon black with a smaller particle size causes the decrease in particle size of the toner and improves thermal and colorimetric properties of the toner.
