Abstract
An image forming apparatus includes an electrophotographic photoreceptor that includes a conductive substrate, an undercoat layer provided on the conductive substrate, containing a binder resin and an electron transport material, and satisfying Expression 1-1, and a photosensitive layer provided on the undercoat layer, a charging device that charges a surface of the electrophotographic photoreceptor, an electrostatic latent image forming device that forms an electrostatic latent image on the charged surface of the electrophotographic photoreceptor, a developing device that develops the electrostatic latent image formed on the surface of the electrophotographic photoreceptor with a developer containing a toner to form a toner image, and a transfer device that transfers the toner image to a surface of a recording medium, in which a moving time of an outer peripheral surface of the electrophotographic photoreceptor, required from charging performed by the charging device to development performed by the developing device, is 90 msec or longer,
