1. A toner comprising:
a toner particle that contains a binder resin and an organic silicon polymer, wherein the organic silicon polymer has a structure represented by the following formula (T3), a proportion of the structure represented by the following formula (T3) to the number of a silicon atom in the organic silicon polymer is at least 5.0%, the toner particle contains a polyester resin of from at least 1.0% by mass to less than 80% by mass, and the polyester resin is at least one polymer selected from the group consisting of: a polymer obtained by condensation polymerization of an alcohol component containing at least 50.0 mol % of an aliphatic diol having from 2 to 16 carbon atoms in an alcohol component, and a carboxylic acid component containing at least 50.0 mol % of an aliphatic dicarboxylic acid having from 2 to 16 carbon atoms in a carboxylic acid component, a polymer obtained by condensation polymerization of an alcohol component containing at least 50 mol % of an aliphatic diol having from 2 to 16 carbon atoms in an alcohol component, and a carboxylic acid component containing at least 50 mol % of an aromatic dicarboxylic acid having from 2 to 16 carbon atoms in a carboxylic acid component, and a polymer obtained by condensation polymerization of an alcohol component containing at least 50.0 mol % of an aromatic diol in an alcohol component, and a carboxylic acid component containing at least 50.0 mol % of an aliphatic dicarboxylic acid having from 2 to 16 carbon atoms in a carboxylic acid component:
[Chemical Formula 1]Rf—SiO3/2 (T3)(wherein, Rf represents a hydrocarbon group having from 1 to 6 carbon atoms or aryl group). |
