PROBLEM TO BE SOLVED: To provide a toner simultaneously realizing low-temperature fixability, hot offset resistance and storage stability at a high level, allowing lower temperature fixation than before, suppressing end offset, and having excellent storage stability.SOLUTION: The toner comprises: toner particles including a binder resin, a release agent and a coloring agent; and inorganic fine particles. A main peak molecular amount of tetrahydrofuran soluble fraction of the toner measured by gel permeation chromatography is 8.0×10or larger and 3.0×10or smaller. The toner is toluene-extracted under a condition at 150°C and 10 MPa. A toluene insoluble volume derived from the binder resin with an extraction time of 50 minutes is set as A (mass %), and a toluene insoluble volume derived from the binder resin with an extraction time of 125 minutes is set as B (mass %), a value obtained by subtracting B from A is 0 or larger and 10 or smaller, and B is 10 or larger and 35 or smaller. |
