  • Patent number: 8283099
    Abstract: Disclosed are a biomass chemical toner composition and a method for manufacturing the same. First, a biomass resin is mixed with a first hydrophobic resin to form organic particles. The organic particles, a second hydrophobic resin, and a pigment are mixed by emulsion aggregation to form cores. Subsequently, a third hydrophobic resin is formed on the surface of the cores, and the third hydrophobic resin is further heated and coalesced to form a continuous structure encapsulating the cores. Accordingly, the biomass chemical toner obtained from the described method has good anti-humidity, good charge stability, and low fusing temperature.
