Abstract
A toner comprising a toner particle, wherein the toner particle comprises a binder resin and wax, and where with respect to a slope X of a straight line obtained by performing a micro-compression test on the toner, obtaining a relationship of a deformation amount (μm) to a load (mN), calculating a percentage deformation (%), which is a ratio of the deformation amount to a particle diameter of the particle measured, plotting a load (mN)-percentage deformation (%) plot, and then using all the points plotted within the range in which the percentage deformation was 15% or less of the particle diameter of the particle for approximation by a least squares method, the slope X measured at 30° C. is denoted by X30 and the slope X measured at 45° C. is denoted by X45, the X30 is 25 to 300, and the X45 is 400 to 1000.
