Claim 14:
15. A resin composition for a toner for development of electrostatic images that comprises an amorphous polyester-based resin A and a crystalline polyester-based resin C, wherein:
the amorphous polyester-based resin A has a polyester resin-derived constituent moiety derived from a polyester resin, and a modified polyolefin-based polymer A-derived constituent moiety derived from a reactive functional group-having modified polyolefin-based polymer A, and the polyester resin-derived constituent moiety and the modified polyolefin-based polymer A-derived constituent moiety are bonded via a covalent bond, and
an amount of the modified polyolefin-based polymer A-derived constituent moiety is from 5% by mass to 15% by mass relative to the total amount of the resin component in the toner.
