摘要： A toner for developing a latent electrostatic image which includes a binder resin and a coloring agent. In the toner, a coverage with the coloring agent on a surface of the toner is 1.5% by atom to 15% by atom, and the toner contains 2% by weight to 15% by weight of the coloring agent. The toner prevents scatterings and toner deposition on the background of images. The toner also enables forming an image having less of the weakly or invertly charged toners, even after printing several tens of sheets at high temperature and in high humidity.
