The thermal characteristics of the color toners, especially Tg , are important because they have a direct effect on the fixing properties of toners onto the paper substrate. A moderate Tg value is gener- ally required for the toner to have appropriate fixing properties. Too high a Tg results in large-scale energy consumption during the prin- ting process; too low Tg will cause the toner to stick to the printer cartridge. For an industrial toner to have suitable fixing proper- ties for energy-efficient laser printing, Tg should normally be in the
range of 50–70 ◦ C [22,23]. Fig. 4 shows the results of DSC analysis of
color toner particles under the best conditions recorded in Table 3.
