    摘要： A toner for developing an electrostatic image excellent in fixing property and particularly in light transmissibility and coloring property and satisfying high image quality and high reliability, and a process for producing the same, as well as a developer for an electrostatic image and a process for forming an image are provided. The toner for developing an electrostatic image contains at least a resin component and colorant particles, and the colorant particles exhibit a dispersion state inside the toner observed by a transmission electron microscope. The dispersion state satisfies two conditions, where (1) the colorant particles have a dispersion average particle diameter of 100 nm or less, and (2) the colorant particles have a content of coarse particles of a diameter of 400 nm or more 5% by number or less of the total of the colorant particles.
