<p>PURPOSE:To obtain a toner excellent in high-speed fixability, fixability at a low temp. and pressure and anti-offsetting property to a fixing roll and having satisfactory blocking resistance by incorporating vinyl resin obtd. by copolymerizing a vinyl monomer with a silane coupling agent having an unsatd. double bond and an alkoxysilyl group as a bonding resin. CONSTITUTION:Vinyl resin obtd. by copolymerizing a vinyl monomer with a silane coupling agent having an unsatd. double bond and an alkoxysilyl group is incorporated as a bonding resin. The vinyl monomer is preferably a styrene monomer such as styrene, alpha-methyl-styrene or chlorostyrene. The content of the silane coupling agent in the vinyl resin can freely be regulated but the silane coupling agent is preferably added by 0.01-0.1 mole percentage per mol of the vinyl monomer to well exhibit the effect of the silane coupling agent.</p> |
