An image forming apparatus comprising:
- a latent image supporting member;
- a charging unit which charges uniformly the latent image supporting member;
- an exposing unit which exposes the latent image supporting member uniformly charged by the charging unit so that an electrostatic latent image is formed on the latent image supporting member;
- a developing device which develops the electrostatic latent image formed by the exposing unit on the latent image supporting member with a toner so that a toner image is formed;
- and
- a transfer unit which transfers the toner image to a recording medium,
- wherein the toner comprises;
- toner base particles;
- resin fine particles comprising a polymer having an isobornyl group-containing acrylate monomer;
- and
- hydrophobic silica.
