Document Type and Number:
Japanese Patent JP7370227
Kind Code:
B2
Abstract:
The invention relates to a toner for development of electrostatic images excellent in fusing property on polypropylene films and excellent in rubfastness of printed images, and a resin composition for a toner for development of electrostatic images. The toner for development of electrostatic images and the resin composition for a toner for development of electrostatic images each contain an amorphous polyester-based resin A and a crystalline polyester-based resin C, wherein the amorphous polyester-based resin A has a constituent moiety derived from a polyester resin, and a constituent moiety derived from a reactive functional group-having modified polyolefin-based polymer A, the polyester resin-derived constituent moiety and the modified polyolefin-based polymer A-derived constituent moiety being bonded via a covalent bond, and the amount of the modified polyolefin-based polymer A-derived constituent moiety is 5% by mass or more and 30% by mass or less relative to the total amount of the resin component in the toner.
