Toner for developing electrostatic images, developer, image forming method, and image forming apparatus

An image forming apparatus comprising:

• a photoconductor,
• a charging unit configured to charge the photoconductor,
• an exposing unit configured to expose the photoconductor charged by use of the charging unit with a write laser beam to form a latent electrostatic image,
• a developing unit with a developer loaded therein configured to develop the latent electrostatic image into a visible image by supplying the developer to the photoconductor to thereby form a toner image, and
• a transferring unit configured to transfer the toner image formed by use of the developing unit onto a transferring member,
• wherein the developer is a two-component developer which comprises a toner for developing electrostatic images and a carrier;
• the toner for developing electrostatic images comprises a colorant, a resin, and a fluoride compound, the fluoride compound exists on the surfaces of toner particles, and the atomic number ratio (F/C) of fluoride atoms to carbon atoms existing on the surfaces of the toner particles is 0.010 to 0.054;
• and the carrier comprises magnetic particles.
