摘要：
An object of the present invention is to provide a toner which allows fixation at low temperatures, which is excellent in anti-offset ability, and which provides a high quality image at high and low humidities in a stable manner without causing any image defect over time. Provided is a toner, containing at least a binder resin and a colorant in which: the binder resin in the toner contains 60% by mass or more of a styrene/acryl resin and a THF-insoluble fraction A which is an extraction residue obtained by carrying out Soxhlet extraction with tetrahydrofuran (THF) for 16 hours; the THF-insoluble fraction A contains a TOL-insoluble fraction B which is an extraction residue obtained by carrying out Soxhlet extraction with toluene (TOL) for 16 hours; and a mass ratio (B/A) between the THF-insoluble fraction A and the TOL-insoluble fraction B is in the range of 0.1≦B/A≦0.5.
