(57) Abstract: A toner resin having excellent low-temperature fixability, gloss and offset properties, good vinyl offset properties, and low cost, and a toner composition thereof are provided. (A) A base resin is reactively melt mixed with a chemical initiator to crosslink the base resin to produce a highly crosslinked precursor resin, the precursor resin being substantially a sol. Free, containing uncrosslinked portions and crosslinked portions, the crosslinked portions comprising dense crosslinked microgel particles; (b) The highly crosslinked precursor resin of (a) is diluted by melt mixing with a base resin and a toner additive to form a partially crosslinked toner resin, the toner resin being substantially sol. A linear uncrosslinked portion and a crosslinked portion, the crosslinked portion including high density crosslinked microgel particles, the microgel particles comprising from about 1 to about 4 of the toner resin. A method for producing a toner resin and a toner composition thereof, which is present in an amount of 5% by weight. |
