Abstract:
1. A toner, comprising: a core particle, the core particle including a resin P, wherein the resin P is a polyester resin having a weight average molecular weight of 3,000 to 20,000; an inner shell layer covering the core, the inner shell layer including fine particles of a resin A; and an outer shell layer covering the inner shell layer, the outer shell layer including fine particles of a resin B, wherein the toner satisfies the following formulae (1) to (3): wherein T½(P), T½(A), and T½(B) represent ½ method temperatures of the resins P, A, and B, respectively, and Tfb(P), Tfb(A), and Tfb(B) represent flow beginning temperatures of the resins P, A, and B, respectively, and wherein the ½ method temperatures and the flow beginning temperatures are measured by a flowtester while setting a load to 30 kg, a die diameter to 1.0 mm, a die length to 1.0 mm, a heating rate to 3° C./min, and a sample amount to 1.0 g.
