ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a toner causing little filming on a photoreceptor while maintaining fixing property and gloss in an oil-less state. SOLUTION: The toner is made of particle aggregates containing amides, hydrazides and aminoalkyl compounds of (meth)acrylic acids as polymer primary particles having positive electrification property and primary particles of amides, hydrazides and aminoalkyl compounds of fatty acids as wax particles having negative electrification property, and coloring agent primary particles. The method for manufacturing the toner is carried out by adding an electrolyte to an emulsified dispersion liquid containing the polymer primary particles, coloring agent primary particles and wax particles and aggregating the particles to obtain particle aggregates. The toner made of particle aggregates contains 1 to 40 parts by weight of the wax to 100 parts by weight of the polymer primary particles.
