<p>PURPOSE:To obtain a toner excellent in blocking resistance and fixable at a low temp. in a heat roller fixing system without using an anti-offsetting liq. CONSTITUTION:Resins (A), (B) each having a specified softening point and different from each other in softening point by >=10 deg.C are mixed as principal components to obtain the objective bonding resin for producing toner. The resin (A) is a resin obtd. by bringing a mixture contg. the raw material monomer of a condensation-polymerized resin, the raw material monomer of vinyl resin and a compd. capable of reacting with both the monomers into a condensation polymn. reaction and an addition polymn. reaction at the same time in the same reactor. The resin (B) is a condensation-polymerized resin. The objective toner contains the bonding resin.</p> |
