Toner characterized in that assuming that the glass transition point of the toner measured by a differential scanning calorimeter (DSC) is represented by T1 (° C.), in a micro compression test at T1−10 (° C.), when a load from 0.00 N (0.00 mgf) to 7.85×10−4 N (80.00 mgf) is applied at the intervals of 7.85×10−7 N (0.08 mgf) to a single particle of the toner, the strain value A80a (%) at 7.85×10−4 N is 35.0 to 75.0%; and in a load (x-axis)-strain (y-axis) curve obtained by the micro compression test, the ratio of an area (S1a) of a specific region, relative to an area (S2a) of a specific region, (S1a/S2a), is 1.5 to 3.5.
A toner comprising toner particles containing at least a binder resin, a colorant and wax, and inorganic fine powder, wherein, assuming that the glass transition point of the toner measured by a differential scanning calorimeter (DSC) is represented by T1 (° C.), in a micro compression test for the toner at T1-10 (° C.), when a load from 0.00N (0.00 mgf) to 7.85×10−4 N (80.00 mgf) is applied at the intervals of 7.85×10−7 N (0.08 mgf) to a single particle of the toner, the strain value A80a (%) at 7.85×10−4 N is 35.0 to 75.0%;
