Abstract:
An object of the present invention is to provide a toner that exhibits high levels of the low-temperature fixability, storability, and charging performance all at the same time. The toner of the present invention is a toner that has a toner particle comprising a crystalline resin and an amorphous resin, the toner being characterized in that the toner satisfies 0.00≤(Wt2/Wt1)≤0.50; the toner particle has a matrix-domain structure in which domains of the crystalline resin are present in a matrix of the amorphous resin; at least 90 number % of the crystalline resin domains are domains with a diameter from 0.05 μm to 0.50 μm; and SF1 for the crystalline resin domains is from 100 to 130.
