TONER

摘要

A toner is provided in which low-temperature fixing properties and high-temperature offset resistance can be compatible, and the environmental stability of image density can also be obtained. A toner obtained by condensation polymerization of an alcohol component containing not less than 70 mol% of an aliphatic polyalcohol with a carboxylic acid component, and including a polyester resin having a concentration of an ester group of not less than 25% by mass and not more than 55% by mass, and a compound represented by the following formula [1] as a charge-controlling agent: (wherein A1, A2, and A3 each independently represent H, a nitro group, or a halogen atom; B1 represents H or an alkyl group; M represents an Fe atom, a Cr atom, or an Al atom; X+ represents a H ion, an alkali metal ion, a NH4 ion, an alkylammonium ion, or mixed ions thereof.)
