Title:
METHOD FOR MANUFACTURING TONER FOR ELECTROSTATIC IMAGE DEVELOPMENT
Document Type and Number:
WIPO Patent Application WO/2016/104656
Kind Code:
A1
Abstract:
The present invention pertains to a method for manufacturing a toner for electrostatic image development, the method including step (1): a step for mixing a releasing agent and an aqueous dispersion of resin particles (A), and obtaining an aqueous dispersion of releasing agent particles; step (2): a step for mixing and aggregating the resulting aqueous dispersion of releasing agent particles and an aqueous dispersion of resin particles (B), and obtaining aggregated particles; and step (3): a step for fusing the resulting aggregated particles and obtaining fused particles, wherein: the resin particles (A) contain a composite resin having a segment (a1) that comprises a polyester resin, and a vinyl resin segment (a2) that contains constituent units derived from a styrene-based compound; and the resin constituting the resin particles (B) contains at least 50 mass% of a segment (b1) comprising a polyester resin.
