Abstract:
A toner comprising toner particles, each toner particle comprising a binder resin, a coloring agent and a releasing agent, wherein said toner particles have a weight-average particle diameter of 5 to 12 .mu.m, containing therein toner particles with a particle diameter of 4 .mu.m or less in an amount of 35% or less in terms of the percentage of the number of toner particles in said toner particles, and said releasing agent has an endotherm ratio (Q/q) of 0.98 to 0.77, that is measured, using a differential scanning calorimeter (DSC), by classifying and sampling toner particles with a weight-average particle diameter of 4 .mu.m from said toner, wherein q is the endotherm (.mu.V.multidot.min/mg) of said releasing agent contained in said sampled toner particles, assessed per unit amount of said sampled toner particles, and Q is the endotherm (.mu.V.multidot.min/mg) of said releasing agent contained in said toner particles of said toner in its entirety, assessed per unit amount of said toner particles.
