ABSTRACT:
The toner for developing a latent electrostatic image to form an image contains a binder resin and 2% by weight to 15% by weight of a coloring agent. The coverage of the toner with the coloring agent on a surface of the toner is 1.5% by atom to 15% by atom. The toner prevents scatterings and toner deposition on the background of images and provides high quality images even after printing several tens of sheets at high temperature and in high humidity.
