Abstract
An image forming apparatus includes an electrophotographic photoreceptor that has a photosensitive layer constituting a surface of the electrophotographic photoreceptor, a charging device that charges the surface of the electrophotographic photoreceptor, an electrostatic charge image forming device that forms an electrostatic charge image on the charged surface of the electrophotographic photoreceptor, a developing device that accommodates a developer containing a toner which contains toner particles and an external additive, and develops the electrostatic charge image formed on the surface of the electrophotographic photoreceptor by the developer as a toner image, a transfer device that transfers the toner image formed on the surface of the electrophotographic photoreceptor to a surface of a recording medium, and a cleaning device that includes a cleaning blade coming into contact with the surface of the electrophotographic photoreceptor and cleaning at least residual toner particles on the surface of the electrophotographic photoreceptor.
