[PROBLEMS] To have excellent fixing properties, fogging, thin density, image unevenness, transfer unevenness, filming and fusion of toner and external additives to the surface of a latent image carrier and developer carrier even in long-term use. A toner that does not cause problems such as fusing to the layer thickness regulating member. A toner having toner particles containing at least a binder resin, a colorant, a wax, a vinyl-modified polyester resin, and a resin having a sulfonic acid or a sulfonic acid base and a sulfonic acid ester, and an inorganic fine powder, the toner The particles are produced by polymerizing in an aqueous medium in the presence of at least the vinyl-modified polyester resin. The vinyl-modified polyester resin has at least a vinyl monopolymer or copolymer unit and a polyester unit chemically. The resin having a molecular structure bonded thereto is contained, and the content of the vinyl-modified polyester resin in the toner is 2.0 to 7.0% by mass. [Selection figure] None |
