Toner for developing electrostatic charge image

A toner for developing electrostatic charge image, comprising:

• a toner particle having a core-shell structure and a binder resin, wherein
• the binder resin comprises a hybrid crystalline polyester resin, a hybrid amorphous polyester resin, and an amorphous vinyl resin,
• the hybrid crystalline polyester resin is formed by chemical bonding between a crystalline polyester resin unit and an amorphous vinyl resin unit, the crystalline polyester unit is formed from a monomer composition comprising an aliphatic dicarboxylic acid having from 4 to 14 carbon atoms and an aliphatic diol having from to 14 carbon atoms through a condensation reaction, and the amorphous vinyl resin unit of the hybrid crystalline polyester resin is a styrene-acrylic resin unit,
• the hybrid amorphous polyester resin is formed by chemical bonding between an amorphous polyester resin unit and an amorphous vinyl resin unit, the amorphous polyester resin unit is formed from a monomer composition comprising an aromatic dicarboxylic acid and a diol selected from ethylene oxide adduct of bisphenol A or propylene oxide adduct of bisphenol A through a condensation reaction, and the amorphous vinyl resin unit of the hybrid amorphous polyester resin is a styrene-acrylic resin unit,
• the amorphous vinyl resin is a styrene-acrylic resin,
• the core contains the hybrid crystalline polyester resin and the amorphous vinyl resin, and
• the shell contains the hybrid amorphous polyester resin.
