Original Abstract Submitted

An image forming apparatus includes a magnetic toner, an image bearing member, and a development device. The image bearing member is an amorphous silicon photosensitive drum. The magnetic toner includes toner particles. The toner particles each include a toner mother particle containing a binder resin and a magnetic powder and alumina particles attached to a surface of the toner mother particle. The alumina particles each include a core containing alumina and a conductive layer covering the core. The conductive layer contains antimony tin oxide. The alumina particles have a number average primary particle diameter of at least 0.15 μm and no greater than 0.50 μm. The alumina particles have a specific resistance of no greater than 250 Ω·cm. The alumina particles have an X-ray intensity ratio of at least 0.25 and no greater than 0.35.
