<p>PURPOSE: To obtain a resin compsn. capable of giving a toner excellent in anti-offsetting property, low-temp. fixability and blocking resistance and having a wide fixing temp. region. CONSTITUTION: This resin compsn. has a matrix phase and a domain phase dispersed in the matrix phase and contains a resin having a wt. average mol.wt. of 5,000-30,000 and >=50 deg.C glass transition temp., based on a styrene monomer and forming the matrix phase by 70-90wt.% of the total amt. of all t.he resins, a resin having a wt. average mol.wt. of 500,000-1,200,000 and <70 deg.C glass transition temp., contg. a (meth)acrylic acid monomer as principal constituent units and forming the domain phase by 10-40wt.% of the total amt. of all the resins and a fixing aid contained in t.he matrix phase and/or the domain phase.</p> |
