Abstract
Provided is a toner satisfying low-temperature fixing performance and long-term storage stability of fixed images. Further, provided is a toner capable of obtaining toner images excellent in long-term storage stability irrespective of use environments even in the case where images are formed by a high-speed fixing system having low internal pressure of a fixing nip of a fixing device and a high printing speed. The toner includes toner particles containing a binder resin having a resin A and B, and a coloring agent, in which the resin A includes a resin including a moiety capable of forming a crystalline structure; the resin B includes a resin free of a moiety capable of forming a crystalline structure; and ΔHand ΔHsatisfy the expressions:2≦ΔH≦453[%]≦{(Δ)/Δ}×100≦70[%]where ΔHand ΔHrepresent a heat of melting derived from the binder resin measured at a temperature increase speed of 100° C./min and 10° C./min, respectively.
