Abstract: A low energy consumption monochrome toner includes a surface additive package having a high charging silica compound, an aerating silica compound, a colloidal silica compound, a polymeric spacer, and a crosslinked spacer. The low energy consumption monochrome toner is suitable for high speed printing in SCD systems while decreasing minimum fusing temperature, maintaining excellent hot offset and storage, and exhibiting a matte finish.

Abstract: A low energy consumption monochrome particle includes a core latex having a core a glass transition temperature and a weight average molecular weight. A shell encapsulates the core and includes a shell latex having a shell glass transition temperature and a weight average molecular weight. The glass transition temperature of the shell latex is higher than the glass transition temperature of the core latex. The weight average molecular weight of the shell latex is lower or higher than the weight average molecular weight of the core latex. The low energy consumption monochrome particles are suitable for high speed printing in SCD systems while decreasing minimum fusing temperature, maintaining excellent hot offset and storage, and exhibiting a matte finish.
