摘要：
A developer for developing an electrostatic image has a toner containing a binder resin and a colorant. The binder resin is comprised of an AB-type block copolymer having segment-A and segment-B.The segment-A has a copolymer structure comprised of a styrene monomer and at least one monomer selected from the group consisting of an acrylic monomer, a methacrylic monomer and a diene monomer, and the segment-B has a copolymer structure comprised of a styrene monomer and at least one monomer selected from the group consisting of an acrylic monomer, a methacrylic monomer and a diene monomer, provided that the segment-A and segment-B have copolymer structures different from each other.
