ABSTRACT:
To provide an image forming method including forming a latent electrostatic image on a latent electrostatic image bearing member, developing the latent electrostatic image using a toner to form a visible image, transferring the visible image to a recording medium, and fixing a transfer image transferred on the recording medium, wherein the toner includes a toner base particle containing at least a binder resin, a colorant and an inorganic fine particle, and a charge control agent; and wherein the condition Xsurf>Xtotalis satisfied (where Xsurfis an average proportion of the inorganic fine particles in a near-surface region of the toner base particle, Xtotalis an average proportion of inorganic fine particles in the whole toner base particle.
