IMAGE FORMING APPARATUS

An image forming apparatus forms an image on a recording medium using first to fourth toners, and includes an intermediate transfer target; a primary transfer unit that transfers a first toner image, a second toner image, a third toner image, and a fourth toner image to the intermediate transfer target in stated order; and a secondary transfer unit that collectively transfers the first to fourth toner images onto the recording medium. The first toner image, the second toner image, the third toner image, and the fourth toner image include the first toner, the second toner, the third toner, and the fourth toner, respectively. The first to fourth toners each include toner particles. The toner particles each include a toner mother particle and an external additive attached to the surface of the toner mother particle. The external additive includes fluororesin particles and silica particles.
