<p><P>PROBLEM TO BE SOLVED: To provide a core-shell toner including a hybrid resin as the core and having excellent releasing property, charging property and durability. <P>SOLUTION: The toner for dry electrostatic charge image development contains at least a binder resin, a colorant, and a release agent, wherein the toner has a core shell structure, and the core contains at least one resin selected from the group consisting of a hybrid resin and a polyester resin, where the hybrid resin is a resin in which a polyester resin and a vinyl resin are chemically bonded to each other, and the shell contains a resin prepared by polymerizing at least a styrene monomer and an ester monomer represented by general formula (1). In general formula (1), R<SB>1</SB>represents a hydrogen atom or an alkyl group; R<SB>2</SB>represents a hydrogen atom, an alkyl group or a phenyl group; n is 2 or 3; and X is any of 0 to 9. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
