PROBLEM TO BE SOLVED: To provide a toner capable of improving a transfer rate without deteriorating fixability, eliminating image defects during transfer, and outputting images with good reproducibility for a long period, in a high-speed full-color image forming method.SOLUTION: A toner includes at least a binder resin; the binder resin includes a polyester resin as a main component, and a layer A comprising a styrene-acrylic resin and a layer B comprising an acrylic resin formed outside the polyester resin; the layer A is formed outside the layer B; both the styrene-acrylic resin and the acrylic resin have a hydroxyl group or a carboxyl group; and each of the resins satisfies a physical property range that is separately described among acid value, volume average particle diameter, weight average particle diameter, and glass-transition temperature. |
