Abstract:
1. A toner, comprising: a binder resin; and a colorant, and satisfying the following relationships (1)-(3): wherein W(3000) represents a percentage of components having a molecular weight of not higher than 3000 in tetrahydrofuran-soluble components of the toner determined by subjecting the tetrahydrofuran-soluble components to a GPC-RALLS viscosity analysis, Mp represents a molecular weight at a peak top of a main peak in a molecular weight distribution curve of the tetrahydrofuran-soluble components obtained by the GPC-RALLS viscosity analysis, Rt(Mp) represents an inertia square radius at the molecular weight Mp, and Rs(Mp) represents an inertia square radius of linear polystyrene at the molecular weight Mp, wherein the inertia square radius Rs(Mp) is determined from a working curve obtained by subjecting plural polystyrenes having different molecular weights to the GPC-RALLS viscosity analysis.
