Abstract:
A toner comprising a toner particle containing a binder resin, a colorant, an amorphous polyester, and a crystalline polyester, wherein the binder resin contains a vinyl resin; the amorphous polyester has a monomer unit derived from a linear aliphatic dicarboxylic acid having 6 to 12 carbons, and a monomer unit derived from a dialcohol; the content of the monomer unit derived from a linear aliphatic dicarboxylic acid having 6 to 12 carbons is 10 to 50 mol % with reference to the total monomer units derived from a carboxylic acid in the amorphous polyester; and in a cross section of the toner particle, the vinyl resin constitutes a matrix and the amorphous polyester constitutes domains, and the crystalline polyester is present in the interior of the domains.
