<p>PURPOSE:To provide a capsulated toner capable of controlling electrostatic chargeability from the inside, excellent in anti-offsetting property in a hot press fixing system with a heat roll, etc., fixable at a low fixing temp., also excellent in blocking resistance and capable of forming clear images free from fog many times. CONSTITUTION:When a capsulated toner for hot press fixation is composed of a heat-meltable core material contg. at least a colorant and a shell formed so as to coat the surface of the core material, the core material is based on a thermoplastic resin obtd. by polymerizing 0.05-20 pts.wt. alpha,beta-ethylenic copolymerizable monomer having an acid anhydride group with 99.95-80 pts.wt. other alpha,beta-ethylenic copolymerizable monomer. The objective capsulated toner for hot press fixation is produced.</p> |
