An image forming apparatus has: a positively-charged single layer type electrophotographic photoreceptor; a charging device with a contact charging roller for charging a surface of the photoreceptor; an exposure device for exposing the charged surface to light to form an electrostatic latent image on the surface of the photoreceptor; a developing device for developing the electrostatic latent image into a toner image; and a transfer device for transferring the toner image to a transferred body. The photoreceptor has a conductive substrate and a photosensitive layer that contains a charge generating agent, a charge transport agent and a binder resin. The binder resin has a yield point strain of 9 to 29%, and the contact charging roller has a conductive layer with a thickness of 1 mm to 3 mm. The image forming apparatus is environmentally responsive and having a long-lasting positively-charged single layer type photoreceptor and charging roller.
