Abstract: A process of forming an image includes the steps of: developing an electrostatic latent image with a toner, the latent image being formed through charge of the surface of an electrostatic latent image carrier and exposure of the surface to light; and applying a lubricant onto the surface of the electrostatic latent image carrier. The toner includes a toner matrix particle and an external additive nanoparticle. The external additive nanoparticle comprises a silica-polymer composite nanoparticle. A percentage of atomic silicon present on the surface of the silica-polymer composite nanoparticle satisfies Condition A expressed by Expression: 15.0 atm %≦percentage of atomic silicon ({Si/(C+O+Si)}×100)≦30.0 atm %. The percentage of atomic silicon is determined from total amounts of atomic carbon, oxygen, and silicon present on the topmost surface of the silica-polymer composite nanoparticle and within 3 nm inwards from the topmost surface.
