Abstract
The present invention provides a toner which is excellent in low-temperature fixability and transparency and has high gloss, and which is excellent in offset resistance, storage stability, and development stability. The toner is characterized in that: a square radius of inertia Rt at a peak top of a main peak in GPC-RALLS-viscometer analysis of tetrahydrofuran (THF) soluble matter when the toner is dissolved in a THF solvent at 25° C. for 24 hours is 1.0 nm to 3.8 nm; and the square radius of inertia Rt and a square radius of inertia Rp at a peak top of a main peak in GPC-RALLS-viscometer analysis of THF soluble matter when linear polystyrene, having an absolute peak molecular weight value at the same value as a main peak value of the toner, is dissolved in a THF solvent at 25° C. for 24 hours satisfy the relationship of Rt/Rp<0.85.
