ABSTRACT:
A toner for developing latent electrostatic images is disclosed, which comprises (a) thermofusible base particles A having a softening point of 80.degree. C. or less, a flow starting temperature of 110.degree. C. or less, and an average particle size of 5 to 25 .mu.m, and (b) small particles B comprising as the main component an organic polymeric material having a softening point at least 5.degree. C. higher than the softening point of the base particles A and no practical softening point, and an average particle size ranging from 0.1 .mu.m or more, but not more than 1/4 of the average particle size of the base particles A, which small particles B are embedded in the surface of the base particles A so as to cover the surface of the base particles A to a depth of less than the particle size of the small particles B.
