ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER

摘要

PROBLEM TO BE SOLVED: To obtain an electrostatic charge image developing toner giving a sedate high-grade solid image while satisfying fixability at low temperature and anti-offsetting property. SOLUTION: The toner has toner particles consisting essentially of a bonding resin and a colorant and a fine powder having a smaller particle diameter than the toner particles and has 2.5-8.9μm weight average particle diameter and 80-135 deg.C softening point. The fine powder contains a blowing agent comprising a fine powder surface-treated with a resin.
