ABSTRACT:
A binder for a toner containing a polyester resin (A); and a block copolymer (B) comprising a block comprising a sequence of ethylene hydrocarbon and/or a conjugated diene hydrocarbon-derived constituent units, and a block comprising a sequence of styrene-derived constituent units; and/or the hydrogenated product of the block copolymer, i.e., the hydrogenated block copolymer. The binder can be used in a toner which can exhibit superior fixing properties, offset resistance, development durability or the like. Thus, it is possible to satisfy the needs of the markets that require a high-speed printer, low-temperature fixing properties or the like. Recycled PET products can also be used for raw materials, thus contributing to the recycle society.
