ABSTRACT:
A toner resin composition, as well as a toner prepared therefrom, are disclosed which are excellent in fixability, offset resistance and storage stability, and which result in reduced occurrence of DF staining.
The toner resin composition includes (a) a vinyl copolymer containing 25 or lower % by weight of molecular species having molecular weights of 200,000 or higher; and (b) 3 to 10% by weight of ethylene-based olefin polymer which has a DSC-determined peak (melting point) within a range of 85-100.degree. C., a weight average molecular weight (Mw) within a range of 500-900, a number average molecular weight (Mn) within a range of 500-900, and a melt viscosity of 10 to 17 cps at 100.degree. C.
